Metropolitan Water Reclamation District of Greater Chicago

President's Annual Message 2017

Over the past three years as president of the Metropolitan Water Reclamation District of Greater Chicago (MWRD) Board of Commissioners, I have had the pleasure of watching the MWRD exceed expectations in improving our environment. During that time, we have taken major steps toward fulfilling our vision statement of "Recovering Resources, Transforming Water." Certainly the pinnacle of these 2017 achievements is the opening of the McCook Reservoir Stage. I, the last of three reservoirs constructed to protect the area waterways from pollution and mitigate flooding. When completed, this reservoir will be the largest of its kind in the world, providing 10 billion gallons of storage. Here is the annual review of other significant accomplishments this year.




Mariyana T. Spyropoulos
President ofthe Board of Commissioners
We had an award winning year
The Water Environment Federation (WEF) honored our work by bestowing us with three major awards at the world's largest annual water quality event, the Water Environment Federation Technical Exhibition and Conference (WEFTEC). The MWRD received two awards both for the completion of the Calumet System of the Tunnel and Reservoir Plan (TARP), as well as a Project Excellence Award for the completion of the nutrient recovery facility at our Stickney WRR The nutrient recovery facility transformed the largest water reclamation facility in the world into a resource recovery facility.
The District received three awards for our creative use of 1.8 mil­lion cubic yards of overburden materials from McCook Reservoir which created Centennial Hill After winning a statewide award for mined land reclamation from the Illinois Department of Natural Resources (IDNR), the MWRD received the Interstate Mining Compact Commission's Kenes C Bowling National Mine Reclamation Award. The National Association of State Land Reclamationists recognized Centennial Hill for Best Innovation in Mining In keeping with our efforts to recover and reuse resources, we are proud to be recognized for successfully reclaiming mined land

We were recognized by the Illinois Water Environment Association and WEF as water leaders from across the state. I was honored to receive the Public Official Award, and the Laboratory Analyst Award was given to Assistant Director of Monitoring and Research Donna Coolidge.
We received three more awards for our shared role in im­plementing UV technology to improve water quality at our O'Brien WRP. The awards include: the American Academy of Environmental Engineers and Scientists 2017 Honor Award for Design, the American Council of Engineering Companies (ACEC) National Recognition Award; and the ACEC of Illinois Honor Award, which recognizes exceptional engineering projects that benefit the public welfare. The O'Brien WRP uses UV technol­ogy to disinfect water as a final layer to its treatment process to reduce pathogenic bacteria in the water being released from the plant into the North Shore Channel. It is considered the largest wastewater treatment UV installation in the world.
Our flood solutions plan for Chicago's South Side claimed the Innovation Award from the Illinois Association for Floodplain and Stormwater Management. The award was presented for work on a pilot stormwater management study that focused on urban flooding in a 17-square-mile residential area covering portions of eight city of Chicago wards on the South Side. The study evaluated how best to scale up green infrastructure (Gl) within the urban landscape of Chicago to eliminate basement backups and alleviate street flooding.

Wc implemented a new compost and yard waste program
Our Monitoring & Research Department introduced two new programs this year. This summer, we began offering exceptional quality compost at two locations. Our compost is a product of water treatment that improves soil quality by supplying organic matter, improving soil structure and porosity for a better plant root environment, and retaining nutrients longer which allows plants to more effectively utilize them. This blend is effective, economical and already popular with gardeners, park districts, golf courses and landscapers. In fact, the compost had a dra­matic effect on an unused piece of property in Franklin Park, turning it into a garden with 12-foot sunflowers and 18-inch corn husks. We also provided 110 tons of compost in collaboration with the Cook County Sheriff's office, the Ford Heights Park District, the Baseball Tomorrow Fund, Cubs Charities, James McHugh Construction, the U S Army Corps of Engineers and other partners to deliver a state-of-the-art baseball field in Ford Heights. The field provides young baseball players an opportunity to play on a local field instead of having to travel to
neighboring suburbs which previously hampered local involve­ment. What once was a team of 10 players traveling without a home field expanded to a league of five teams consisting of 55 11- and 12-year-olds playing ball games on their regulation-size youth baseball field.
In September, we delivered 300 tons of compost to the Skokie Park District for the construction of a youth soccer field that will be unveiled next year. We have also partnered with other municipalities and park districts to distribute this sustainable resource that improves soil structure and is beneficial to our environment.
The second program pertains to our acceptance of yard waste and other organic materials to help produce the compost. Municipalities, park districts, landscape maintenance companies, yard waste haulers, tree trimming companies and utilities look­ing to unload bulk piles of woodchips are invited to participate in the program.

We pursued water reuse
In keeping with our resource recovery model, the MWRD Board of Commissioners agreed to establish an introductory price of $1 per thousand gallons for the clean water we produce with the flexibility to adjust the price based on market conditions. Water reuse involves recycling treated water for beneficial pur­poses such as agricultural and landscape irrigation, industrial processes, toilet flushing, and replenishing the ground water basin. In addition to being harnessed, water itself is also reused directly through the MWRD treatment process Every day, 15.1 million gallons are reused in pipeline flushing, blower motor cooling, post-centrifuge centrate flushing and tank cleaning. When used appropriately, recycled water can satisfy many water demands while presenting financial savings and promoting water conservation by decreasing the diversion of water from sensitive water bodies like Lake Michigan. We are exploring partnerships and different opportunities to ensure this water can find new opportunities which will, in turn, strengthen our role as stewards of our water environment

We continued restoring the canopy
We continued our popular program. Restore the Canopy Plant a Tree, designed to help Cook County and its residents manage an increasing load of stormwater and replace the tree canopy that has been devastated by the emerald ash borer and severe weather Besides greening our communities, the trees assist in stormwater management by absorbing stormwater and lessen­ing the load to our sewer systems. I'm pleased to report that since the program started in mid-2016 we have distributed more



10 INTRODUCTORY SECTION

A ribbon cutting ceremony to mark the completion of the 3.5 billion gallon McCook Reservoir Stage 1 was held December 4, 2017. Stage I is estimated to provide $114 miilion per year in flood reduction benefits to 3.1 million people in Chicago and 36 other communities When McCook Reservoir Stage II is completed, the reservoir will have a total storage capacity of 10 billion gallons and deliver an estimated total of $143 million per year in flood reduction benefits.
than 42,000 saplings. To aid in this effort, the MWRD partners with dozens of municipalities, schools, and community groups to distribute the trees.

Wc continued our partnership with the Space to Grow program
Our award winning Space to Grow program gained widespread national recognition when the US Water Alliance acknowledged this partnership for its ability to maximize environmental and community benefits through the transformation of local school­yards. The collaborative program converts Chicago schoolyards into community spaces for physical activity, outdoor learning, environmental literacy and engagement with art, while also addressing neighborhood flooding issues The projects serve a vital purpose in educating school communities about the value of green infrastructure. Our engineers are sharing their design expertise in planning for the next five schools to be built in 2018 The Space to Grow program was highlighted in the national briefing paper, An Equitable Water Future," as a case study that exemplified how water infrastructure investments
can lead to neighborhood revitalization. The Space to Grow project was named one of the Top Projects for 2017 by Storm Water Solutions magazine.

We hosted two diversity outreach vendor fairs
To expand and maximize business opportunities for local Minority Business Enterprises (MBE), Women Business Enterprises (WBE) and Small Business Enterprises (SBE), we welcomed hundreds of contractors, consultants, subcontrac­tors and potential vendors during two vendor outreach fairs Participants met with MWRD officials and other firms to learn how to register as a vendor and secure work opportunities with contractors and the MWRD.

We began accepting liquid waste for enhanced biological phosphorus removal (KBPR)

from local breweries as well as sugary and starchy liquid wastes. What makes this waste special for the EBPR process is the readily biodegradable carbon that serves as food for the phosphorus accumulating organisms that work under anaerobic and aerobic conditions in the secondary treatment.

Wc helped launch Overflow Action Days
We joined the Friends of the Chicago River in launching the Overflow Action Days initiative to educate area residents to use less water at home when weather forecasts predict sig­nificant rain, thus giving sewers more capacity to handle rain and improving our water environment. Overflow Action alerts remind people to conserve water before and during rain events. Actions such as delaying showers or reducing their duration, flushing less, and waiting to run the dishwasher can help reduce the amount of water in the sewer system. If our residents keep water from entering the water treatment system, there will be more space in the sewers to accommodate rain water and our waterways will be cleaner. We were reminded throughout the year of the importance of conserving water at home after several significant rain events impacted our region.

We celebrated
We believe in paying tribute to significant groups and occasions throughout the year. This year we celebrated African American History Month by inviting a panel of former aldermen that served under Mayor Harold Washington
During National Engineers week February 19-26, the many contri­butions of engineers were commemorated by the MWRD Board of Commissioners through a resolution celebrating National Engineers Week Engineers Week provides an opportunity for engineering professionals to extol their impact on the world and increase public dialogue about the need for future engineers and their work.
In March, the MWRD celebrated Women's History Month to honor the more than 500 women employed by the MWRD Three employees received specific recognition for contributions in their respective fields as supervising environmental specialist, environmental chemist, and engineering technician
As part of our annual recognition for Veteran's Day, we hon­ored the military service of Secretary of State Jesse White and Assistant Director of Illinois Department of Veteran's Affairs Harry F. Sawyer. As with all of our men and women who serve, we are thankful to Secretary White, Assistant Director Sawyer, and our own district employees who served, for their sacrifice on behalf of this country.|1010|We educated
We participate in more than 100 community events every year to discuss our work. In addition to providing tours of the McCook Reservoir and our facilities, commissioners and staff give hundreds of presentations throughout the county. This year, the MWRD facilitated WaterPalooza and an outdoor garden construction event at Manierre Elementary School to kick off WEFTEC 2017 in September. WaterPalooza is a fun day of hands-on environmental activities for students and teachers. The following day, volunteers and water experts transformed a paved, flood-prone area into an outdoor classroom that will also capture stormwater. MWRD coordinates this effort every other year with other government agencies, elected officials and water companies. Manierre School is also our Working in the Schools (WITS) partner where MWRD staff visitonce a week to read to students.
We held our fifth annual Sustainability Summit at the Stickney Water Reclamation Plant (WRP) in October. This event offers local government leaders, park districts, landscapers and others to learn about our initiatives, specifically our biosolids and new compost program.
In pursuit of our ongoing goal of providing safer and cleaner wa­terways, the MWRD set up permanent collection boxes for safe disposal for unused and expired medication at four locations. We also continue to partner with the U.S. Drug Enforcement Agency's National Prescription Drug Take Back Days.
MWRD produced a new brochure entitled "A healthy waterway begins with you: A Guide to Water Wellness.' Readers are en­couraged to consider how they can make lifestyle modifications that will result in fewer contaminants entering the waterways.

Commissioner Timothy Bradford Passes
Commissioner Timothy Bradford passed away suddenly on December 1. Tim was not only a colleague, but a mentor, a con­fidant, an entertainer, and most importantly, a dear friend. He was larger than life, and his passing has left our Board shocked and saddened Tim was a proud man He was proud of his family, proud of his work in the community, proud of the help he was able to give to so many people throughout his life. And we, the Metropolitan Water Reclamation District, are so very proud to be able to claim him as one of our own Tim. we love you, we miss you, and we promise to carry on the important work you did for the people of Cook County

To the Citizens ofthe Metropolitan Water Reclamation District of Greater Chicago and to the Financial Community:
The Comprehensive Annual Financial Report (CAFR), of which this transmittal letter is a component, has been prepared in accordance with Chapter 70, Illinois Compiled Statutes, Act 2605/5.13, for the fiscal year ended December 31,2017. This statute requires that the Clerk/Director of Finance prepare and publish the financial statements and any other data necessary to reflect the true financial condition and operations ofthe Metropolitan Water Reclamation District of Greater Chicago (the District) within six months ofthe close of each fiscal year.
The CAFR's basic financial statements have been prepared in conformance with generally accepted accounting principles (GAAP) in the United States of America, promulgated by the Governmental Accounting Standards Board (GASB). In accordance with Chapter 70, Illinois Compiled Statutes, Act 2605/5.12, the District's basic financial statements for the period ended December 31, 2017, have been subject to an audit by independent accountants. The unmodified opinion ol'RSM US LLP has been included in the Financial Section of this report.
District management assumes full responsibility for the completeness and reliability of all the information presented in this report. To provide a reasonable basis for making these representations, management ofthe District has established a comprehensive internal control framework that is designed both to protect the government's assets from loss, theft, or misuse and to compile sufficient reliable information for the preparation ofthe District's financial statements in accordance with GAAR The cost of internal controls should not outweigh their benefits; therefore, the District's comprehensive framework of internal controls has been designed to provide reasonable assurance, rather than absolute assurance, that the financial statements will be free from material misstatement. Management understands the risks of financial processing and has implemented procedures to evaluate the effectiveness of these controls. District management and Internal Audit staff continually evaluate the internal control structure.
Both the investment community and taxpayers rely on the CAFR for basic information about the District, its past performance, current financial condition, future plans, and services provided. Financial data and the facts contained herein create an indispensable profile for potential bond investors. Taxpayers can, with full confidence, assess the level, efficiency, and effectiveness ofthe services provided and the related costs.
GAAP requires thai management provide a narrative introduction, overview, and an analysis to accompany the basic financial statements in the form of a Management's Discussion and Analysis (MD&A). This letter of transmittal is designed to complement the MD&A and should be read in conjunction with it. T he District's MD&A can be found immediately following the independent auditor's report.




INTRODUCTORY SECTION 17

MISSION STATEMENT
The District will protect the health and safety ofthe public in its service area, protect the quality ofthe water supply source (Lake Michigan), improve the quality of water in watercourses in its service area, protect businesses and homes from Hood damages and manage water as a vital resource for its service area. The District's service area is 882.1 square miles of Cook County, Illinois. The District is committed to achieving the highest standards of excellence in fulfilling its mission.
BACKGROUND
The District was originally organized as the Sanitary District of Chicago in 1889 under an act of the Illinois General Assembly. The enabling act was in direct response lo a typhoid and cholera epidemic. The District reversed the How ofthe Chicago and Calumet River systems to divert contaminated water from Lake Michigan so it could be diluted as it flowed downstream into the Mississippi River. Subsequently, the District built collection treatment facilities to treat sewage in an environmentally effective manner.
The District operates primarily within the boundaries of Cook County. Although the District exercises no direct control over wastewater collection and transmission systems maintained by cities, towns, and villages in Cook County, it does control municipal sewer construction by permits in suburban Cook County. Furthermore, the District provides the main sewer lines for the collection of wastewater from local sewer systems together with the treatment and disposal thereof. Combined sewage and stormwater runoff is stored, treated, and released using District facilities. The District owns and operates seven water reclamation plants (WRP) and 23 pumping stations that treat an average of 1.3 billion gallons of wastewater each day. The Central (Stickney) WRP is the largest plant in the world. The District controls approximately 76.1 miles of navigable waterways that serve as headwaters ofthe Illinois Waterway system. Stringent federal and state standards require that the District's wastewater treatment processes keep the waterways free of pollution. The District monitors industries in Cook County to assure that hazardous substances not suitable for a sewer are disposed of in an environmentally responsible way that complies with applicable laws.

The multi-award winning Metropolitan Water Reclamation District of Greater Chicago is headed by the Board of Commissioners who determine its policies. (Sealed L to R) Vice President Barbara J.

18 INTRODUCTORY SECTION

REPORTING ENTITY
T he District is governed by a nine-member Board of Commissioners, elected at large for six-year terms. The terms are staggered so that three commissioners are elected every two years. The Executive Director, who is appointed by the Board of Commissioners, manages and controls all District operations and serves as the Chief Executive Officer.
The District is a separate legal entity sharing an overlapping tax base with the City of Chicago, the Chicago Board of Education, the County of Cook, the Cook County Forest Preserve District, the Chicago Park District, the Chicago Public Building Commission, the Cily Colleges of Chicago, and various municipalities and school districts outside the City of Chicago but within the District's boundaries. However, these governments do not meet the established criteria for inclusion in the reporting entity and are therefore excluded.
Improve Water Quality
The District cost effectively collected and treated approximately 453.7 billion gallons of wastewater from businesses and homes and captured stormwater runoff from its service area. Our performance for treating this wastewater approaches 100 percent compliance with all applicable effluent standards at all water reclamation plants. Disinfection technology has been implemented and placed into service at two plants using multiple cost-effective strategies. Chlorination/de-chlorination has been implemented at the Calumet Water Reclamation Plant and ultraviolet technology at the O'Brien Water Reclamation Plant.
Provide Stormwater Management
Flooding continues to be the number one issue facing the District. The Stormwater Management Program is aggressively working to minimize flooding damage by helping communities with local flooding issues, acquiring flood-prone properties, and partnering with municipalities or other local governments on large capital green infrastructure projects. Since 2004 the District has distributed more than 139,800 low-cost rain barrels, and in 2017, the District distributed more than 42,000 tree saplings as a part ofthe "Restore the Canopy, Plant a Tree" initiative.
The District undertakes stormwater management projects under two phases of its Stormwater Management Program. Phase 1 consists of projects identified under Detailed Watershed Plans (DWPs), which were completed in 2010. Phase I projects address regional waterway overbank flooding and streambank stabilization concerns. The District performed construction work on three Phase I projects in 2017, two of which were substantially completed. It is anticipated that an additional eight Phase I projects will begin construction in 2018. The design of two Phase 1 projects were completed in 2017 and are scheduled to begin construction in 2019. '
The District initiated Phase II of its Stormwater Management Program in 2013 to address local Hooding problems not necessarily involving overbank flooding. Since then, the District accepted 40 Phase 11 projects into its program in order to assist communities and agencies across Cook County in addressing flooding issues. Since 2014, a total of 17 shovel ready projects were completed with partial District funding. Construction on one Phase II conceptual design project will begin in 2018 while another conceptual design project may start construction later that year. The remaining 21 projects (12 conceptual and 9 shovel ready) are currently in cither preliminary, final design, or construction. It is anticipated these projects will complete construction or start construction in 2018 and beyond.
For circumstances where a flood control project is not feasible, the District initiated a Flood-Prone Properly Acquisition Program in 2015 and has partnered with nine local municipalities in order to remove nearly a total of 200 structures from the floodplain. Once all 200 properties have been removed, deed restrictions will be imposed and recorded, requiring the properties to remain as open space into perpetuity. The municipalities will own the acquired properties and perform all required maintenance. In late 2017. the District initialed another call for Flood-Prone Properly projects and will soon partner with additional municipalities to remove more properties from the floodplain.
On October 3, 2013, the District's Board of Commissioners adopted the Watershed Management Ordinance (WMO). which replaced the Sewer Permit Ordinance and established uniform, minimum, countywide stormwater management regulations for new development and redevelopment in Cook County. Components regulated under the WMO include drainage and detention, volume control, floodplain management, isolated wetland protection, riparian environment protection, and soil erosion and sediment control. The WMO became effective on May 1, 2014. The siormwater management regulations ofthe WMO serve to prevent the Hooding situation in Cook County from worsening through

INTRODUCTORY SECTION 19

development or redevelopment. Over 1,200 WMO permits have been issued to date. Since the development of the WMO, the District has conducted numerous training events in addition to presenting at various seminars and conferences hosted by professional organizations.
Provide flood protection with Tunnel and Reservoir Plan and Green Infrastructure
The primary goals of TARP are as follows: protect Lake Michigan, the area's primary source of drinking water from polluted backflows; clean up the area's waterways; and provide an outlet for floodwater and rainfall runoff by capturing wastewater before it enters streams and rivers from within the District's service area. TARP consists of 109.4 miles of deep rock tunnels designed to capture 2.3 billion gallons ofthe first flush of sewage contaminated stormwater from combined sewers which had previously flowed into the area waterways.
The flood control segment of TARP consists of three storage reservoirs to serve as outlets for combined sewer overflows (CSO's). The three reservoirs - Gloria Alitto Majewski, Thornton, and McCook - will provide 15.2 billion combined gallons of storage for CSO's that otherwise would spill into local waterways, degrading the water quality and causing Hooding. The Gloria Alitto Majewski Reservoir, the smallest ofthe three, was completed in 1998 al a cost of $45 million and has prevented over 5.7 billion gallons of combined sewer overflow from entering the waterways and mitigated over $400 million in flood damage. The Thornton Composite Reservoir became operational in 2015 and, through the end of 2017, more than 14.4 billion gallons have been captured during 32 fill events. The first stage ofthe McCook Reservoir was completed in 2017 and the second stage will be completed in 2029. The McCook Reservoir is projected to bring SI43 million per year in flood reduction benefits to its residents when fully completed. The combined engineering, construction and land rights cost for all three reservoirs is estimated at $1.48 billion, with the Corps and the District providing approximately $540 million and $940 million, respectively.

TUNNEL and RESERVOIR PLAN PROJECT STATUS
A consent decree between MWRDGC and the U.S. Department of Justice was entered into in 2014. One section of the consent decree is designed to foster the use of green infrastructure controls to reduce the amount of stormwater that Hows into the sewer systems during a storm and requires MWRDGC to develop a Green Infrastructure Program Plan, which was approved by the Environmental Protection Agency in 2015. In 2014, MWRDGC partnered with Chicago Public Schools System (CPSS) and the Chicago Department of Water Management (CDWM) to incorporate stormwater retention at four elementary schools while reconstructing substandard playgrounds under a program known as Space to Grow. The projects serve to educate the public on the importance of stormwater management and the value ofgrecn infrastructure to reduce basement backup flooding. The success of this project led to MWRDGC, CPSS, and CDWM to agree to partner on 30 more schools from 2015 through 2020. In 2015 and 2016, five more CPSS school playgrounds were completed, and design is underway for six additional schools to be improved in 2018. The District completed construction of a green infrastructure project in the City of Blue Island, where permeable pavement and rain gardens were installed to combat local Hooding. The District partnered with the City of Evanston to install permeable pavement, swales, and rain gardens at the City's Civic Center, and also partnered with the Village of Wilmette to install four green alleys. In 2016, the District partnered with the Village of Northbrook in its installation of a green stormwater detention system at Wescott Park, and also partnered with the Village ofKenilworth on rain garden installations. In 2017, the
The Water Environment Federation s Young Professionals Committee worked with community members, teachers and students at Manierre Flementarv School in Chicago to convert a portion ofthe school s asphalt playground into a multipurpose given space and outdoor classroom, featuring native plants and pervious surfaces that will enhance, the property and capture stormwater.

22 INTRODUCTORY SECTION

District completed the construction of a permeable parking lot at its John E. Egan Water Reclamation Plant. The District also partnered with the City of Berwyn on a green alley project, and the Village of Niles on a bioswale and permeable parking lot. In 2017, the District also solicited information from Cook County communities and other governmental organizations for additional green infrastructure partnership opportunities. Based on the project submittals received, the District intends to partner on an additional 20 green infrastructure projects throughout its service area beginning in 2018. The consent decree provides an enforceable schedule for implementing MWRDG's Tunnel and Reservoir Plan, which will result in a significant decrease in the volume of water discharged to the waterways from combined sewer overflows in Cook County, along with dramatically reducing the potential for flooding.

Maintenance of Facilities and Infrastructure
The District owns and operates seven water reclamation plants, 560 miles of intercepting sewers and force mains, 109.4 miles of TARP tunnels, 23 pumping stations, 35 flood control reservoirs, and three TARP reservoirs. Through preventative maintenance management, modernization, rehabilitation, and planned replacement, the District will ensure the long-term reliability and cost-effectiveness of operations. To aid planning and prioritize projects for both near term and long term, the District implemented procedures for project vetting and Long-Term Capital Plan evaluation.
Many ofthe District's plants and interceptor sewers were placed in service over 50 years ago. In order to maintain continuous operations, the District has initiated a Capital Improvements Plan to replace physically deteriorating facilities through rehabilitation, alteration or expansion. The expected construction cost over the next five years for the replacement and maintenance of facilities is S126.4 million. As discussed in the MD&A, condition assessments required under the modified approach alert management to the need for maintenance and preservation projects for its infrastructure assets.
RESOURCE RECOVERY
The District understands the obligation lo implement sustainable practices and has maintained that focus for the past few years by investing in research and development of resource recovery programs. The current sustainability effort is focused on recovering phosphorous, biosolids, water, and energy.
Phosphorus
The District had voluntarily sought a phosphorus discharge limitation in our National Pollutant Discharge Elimination System (NPDES) permits and had decided we would pursue achieving this through our biological process. With one of the District's objectives of sustainability, at ihe Stickney WRP, the District is pursuing the recovery of phosphorus. In partnership with Ostara Nutrient Recovery Technologies, startup ofthe world's largest nutrient recovery facility occurred in May 2016 and is in the operational testing phase of the construction contract. Phosphorus is recovered from the plant's liquid waste stream and turned into a fertilizer pellet, which is marketed and distributed. Construction ofthe Waste Activated Sludge Stripping to Remove Internal Phosphorous (WASSTRIP) process began in June 2016. This process will be operational by the spring of 2018 and will further increase the recoverable phosphorous by repurposing existing tanks in combination with the Ostara process to remove magnesium ammonium phosphate from wasted active sludge. Phosphorus and nitrogen recovery will provide significant environmental benefits to the Chicago Area Waterway System and downstream through the Mississippi to the Gulf of Mexico. By taking this approach, the District is recovering a non-renewable resource and placing it back into the food cycle, rather than letting it be diluted and lost to the water environment.
In fulfillment ofthe special provisions ofthe O'Brien Water Reclamation Plant's (OWRP) NPDES permit, the District has created an Algae Research Facility at the OWRP. This facility carries out research on treatment technologies using algae to recover phosphorus from the wastewater. Algae treatment technology has several advantages over the traditional chemical precipitation approach including the ability to recover and reuse the phosphorus, the ability to generate revenue through sale ofthe harvested algae as a raw material for sustainable commodity products, sequestration of atmospheric carbon dioxide, and use of natural energy from sunlight. Currently, the District has promising results from a one-year study from a technology that cultivates algae using a revolving biofilm reactor, and will continue with a larger pilot-scale research project in 2018. In addition, in 2018 the District will be evaluating the results of another year-long bench-scale algae treatment technology thai uses submerged artificial light in a flow-through configuration. Results from these pilot studies will be used to inform the projected performance, life cycle costs, and design criteria for a full-scale installation at the OWRP.

Biosolids
Due to changes in Illinois law, the District can sell Exceptional Quality (EQ) biosolids and EQ biosolids blend that is composted with wood chips to the general public. By taking this approach, the District is recovering a non-renewable resource and placing it back into the food cycle, rather than letting it be diluted and lost to the water environment. Biosolids can be used almost anywhere that chemical fertilizers are used. The District can also reduce its carbon footprint by reducing significant vehicle traffic as organics will no longer need to be hauled to landfills.
Water
Efforts have been focused on reuse applications for the high quality water produced at the plants and the capture and reuse of stormwater. Reuse opportunities are being explored at the Calumet and Stickney industrial corridors. The District is also exploring reuse at parks and golf courses.
The District is also researching technologies using algae as a means to recover nutrients from wastewater. The algae can be used in a sustainable manner such as compost, aquaculture food supplement, bio plastics, and commercial dyes.
Energy
The District's goal is to achieve energy neutrality by 2023. The anaerobic digesters at the Calumet and Stickney Water Reclamation Plants produce biogas as a natural byproduct ofthe digestion process. The biogas contains methane gas, which is currently used as fuel for the plants' boilers. A significant step towards the District's goal of becoming energy neutral will be the utilization ofthe biogas to produce renewable energy. The Stickney WRP currently utilizes all of their digester gas. Once the existing lmhoff tanks are replaced with Primary Settling tanks, the Stickney WRP is projected to double digester gas production. A plan is in place to fully utilize all of this additional gas production. The digester gas utilization at the Calumet WRP is being reviewed and a utilization plan will be in place m April 201 S. In order to boost biogas production, the District will accept liquid organic wastes, such as restaurant grease and industrial food waste, into the anaerobic digesters under the Resource Recovery Ordinance, which was approved by the Board

of Commissioners in 2016. To handle the incoming feedstock, a new Liquid Organic Waste Receiving Station will be constructed at the Calumet WRR Design ofthe receiving station is complete. Similar work will occur at the Stickney WRR Existing initiatives are also being examined for further reduction of energy consumption. The District is looking to maximize use of digester capacity al the Stickney WRP. market electrical capacity at Lockport to maximize return on investment and optimize the aeration processes to further reduce energy consumption by 25%.

BUDGET PROCESS
The Board of Commissioners is required to adopt an annual budget no later than the close ofthe previous fiscal year. This annual budget serves as the foundation for the Metropolitan Water Reclamation District's financial planning and control. Annual budgets are prepared for ihe General Corporate, Construction, Capital Improvements Bond, Storm­water Management, and Debt Service Funds.
The District utilizes an enteiprise resource planning computer system to provide budget control at the line item level for the General Corporate, Construction, and Stormwater Management Funds, at the fund level for the Debt Service Fund, arid at the line item class level for the Capital Improvements Bond Fund. All budget-relevant transactions arc tested for the sufficiency of available appropriation before any obligations resulting from purchase requisitions, purchase orders, or contracts are formally recognized, or payments resulting from payroll or other expenditures are released.
ECONOMIC BASE OUTLOOK
The District's service area is sizeable, encompassing 98% of the assessed valuation of Cook County. The Equalized Assessed Valuation (EAV) ofthe District has experienced a .24% average growth rate over the last ten years and the current equalized assessed valuation of $140,752,201,171 is 8.0% higher than the previous year. A strong fund balance, along with an emphasis on controlling expenditures, should allow the District to protect its operations from economically sensitive revenues stemming from fiscal constraints at the federal and state levels. The District operates a fiscally sound organization, maintaining a AAA bond rating with Fitch Ratings and AA+ with Standard and Poor's. Our finances are managed in a prudent manner, as evidenced by our excellent bond ratings, healthy fund balance, and continuing efforts to manage costs. To ensure that the District's finances remain healthy, projects are prioritized to ensure best use of current funding, project base budget targets assure funding above the base are tied lo strategic initiatives, and resources are managed lo ensure financial stability targets arc met.
FINANCIAL POLICIES
In order to protect the strong financial position ofthe District, ensure uninterrupted services, and stabilize annual tax levies, the Board of Commissioners adopted the following policies on December 21, 2006 to enhance and maintain budgetary fund balances. The General Corporate Fund policy was amended on December 10, 2009. The Bond Redemption & Interest Funds Investment Income policy was amended on November 3, 2011. The Stormwater Management Fund policy was adopted on December 10, 2009 and amended on November 3. 2011 and December 17, 2015.
To ensure the long-term financial health of the pension program and other post-employment benefits, the Pension Funding Policy and the amended OPF.B Advance Funding Policy were adopted on October 2, 2014.
General Corporate Fund
Corporate Fund undesignated fund balance as of January I of each budget year is lo be kept between 1 2 percent and 15 percent of appropriations. The fund balance may be maintained by not fully appropriating prior year fund balances. This level of fund balance will ensure the District's ability to maintain all operations even in the event of unanticipated revenue shortfalls and provide time to adjust budget and operations.
Corporate Working Cash Fund must be sufficient to finance 95 percent of ihe full annual expenditure ofthe Corporate Fund. - This will be financed through transfers of surpluses from the Construction Working Cash Fund, direct tax levies, lax levy financed debt (Working Cash Bonds) and transfers of accumulated interest


INTRODUCTORY SECTION 25
I

from other funds. This level of fund balance will continue financing the Corporate Fund in the event ofthe typical and extraordinary delays in second installment real estate tax collections.
• Reserve Claim Fund balance will be targeted toward the maximum level permitted by statute, 0.05 percent of the Equalized Assessed Valuation, whenever economically feasible. This will be financed through tax levies at the maximum 0.5 cents per SI00 of Equalized Assessed Valuation when economically feasible and financially prudent. This level of funding will protect the District in the event that environmental remediation costs cannot be recovered from former industrial tenants of District properties, catastrophic failure of District operational infrastructure or other claims. As the District is partially self-insured, adequate reserves are critical.
The District will appropriate funds from the unassigned fund balance for emergencies as well as for other requirements that the District believes to be in its best interest. In the event that any of these specific component objectives cannot be met, the Executive Director will report this fact and the underlying causes to the Board of Commissioners with a plan to bring the fund balances back into compliance with policy within a two-year period. In order to maintain relevance, this policy will be reviewed every three years following adoption or sooner at the discretion of the Executive Director.
Stormwater Management Fund
The maximum properly lax levy of five cents per $ 100 of Equalized Assessed Valuation for the Stormwater Manage­ment Fund shall be allocated at a maximum two cents per SI00 of Equalized Assessed Valuation to fund operations and maintenance expenditures and the remainder ofthe levy shall fund direct cash outflows for capital and capital-related expenditures and the interest and redemption of general obligation bond issues for capital projects.
Capital Improvements Bond Fund Investment Income
Investment earnings from the Capital Improvements Bond Fund resulting from all future bond issues will fund an equity transfer to the Bond Redemption & Interest Funds and be used to abate property tax levies or for other corporate needs. This practice will also limit the payment of arbitrage rebates.
Bond Redemption & Interest Funds Investment Income (Debt Service Fund)
Fund balances in the Bond Redemption & Interest Funds that might accumulate due to investment income will be identified and used to abate Bond Redemption & Interest property tax levies or for other corporate purposes. These abatements appropriately reduce property tax levies by the amount earned on invested balances above what is necessary for paying principal and interest due over the following 12 months, while still maintaining appropriate fund balances and when not required for other corporate purposes. This policy and the subsequent tax abatements will assist in compliance with the Board of Commissioners' overall tax levy policy, which is not to exceed a five percent increase over the prior year, excluding the Stormwater Management Fund tax levy.
Abatement of Interest Rate Subsidies from Build American Bond Issuances
Interest reimbursement payments related to taxes levied for Build America Bond issuances will be presented to the Board of Commissioners for approval to abate, to be used for any lawful corporate purpose, or a combination thereof as determined as part ofthe annual budget process. Such abatement or alternative lawful use ofthe funds will be presented to the Board of Commissioners for approval prior to any abatement or use of reimbursement funds.
Capital Improvements Bond Fund Accumulated Income
Revenues that have accumulated in the Capital Improvements Bond Fund (CIBF) from investment income, grants, or State Revolving Fund revenues will primarily be used for capital projects. Capital projects are generally in Ihe CIBF; however, capital projects m the Construction or Corporate Funds of critical importance may be financed by transfers from this revenue source. These funds may be transferred to the Bond Redemption & Interest Funds lo be used to abate property taxes or may be used for other corporate needs as necessary.







26 INTRODUCTORY SECTION

Accounting Policies of Fund Balance
The General Corporate Fund is a combination of the Corporate, Working Cash, and Reserve Claim Funds. In the General Corporate Fund, the District considers restricted amounts to have been spent first when an expenditure is incurred for purposes for which both restricted and unrestricted fund balance is available, followed by committed amounts, and then assigned amounts. Unassigned amounts are used only after the other categories of fund balance have been fully utilized. In governmental funds, other than the General Corporate Fund, the District considers restricted amounts to have been spent last. When an expenditure is incurred for purposes for which both restricted and unrestricted fund balance is available, the District will first utilize assigned amounts, followed by committed amounts, and then restricted amounts.
Committed Fund Balance
The District's Board of Commissioners shall establish, modify, or rescind a fund balance commitment by formal action of the Board of Commissioners.
Assigned Fund Balances
The Executive Director may assign amounts of fund balances to a specific purpose. Retirement Fund
The District's Board of Commissioners adopted a Funding Policy recommended by the Retirement Fund Board of Trustees to ensure the long-term financial health ofthe pension program while balancing the interests ofthe employees, retirees, taxpayers, and the District. The funding goal of the policy is to contribute annually to the Fund an amount that will increase the funded ratios to 100 percent by the year 2050. This is to be achieved by accumulating adequate resources for future benefit payments in a manner that fully funds the long-term costs of benefits and reduces volatility in the employer contribution amounts, in accordance with statutory requirements.
OPEB Trust
The OPEB Trust establishes a reserve that will help ensure the financial ability to provide health care coverage for District retirees and their beneficiaries in the future. The Advance Funding Policy for the OPEB Trust Fund, amended in October 2014, reflects a 100 percent funding goal to be achieved by 2027 with no further advance contributions required after 2026. The policy to increase the OPEB liability funding percentage helps to solidify the District's solid financial foundation and makes the retiree healthcare plan sustainable for the long-term.
AWARDS
The Government Finance Officers Association of the United Stales and Canada (GFOA) awarded a Certificate of Achievement for Excellence in Financial Reporting to the Metropolitan Water Reclamation District of Greater Chicago for its Comprehensive Annual Financial Report for the fiscal year ended December 31, 2016. This was the 42nd consecutive year that the Metropolitan Water Reclamation District has achieved this prestigious award.

Independent Auditor's Report
RSM US LLP

To the Honorable President and Members of the Board of Commissioners Metropolitan Water Reclamation District of Greater Chicago
Report on the Financial Statements
We have audited the accompanying financial statements ofthe governmental activities, each major fund, and the aggregate remaining fund information of the Metropolitan Water Reclamation District of Greater Chicago (the District), as of and for the year ended December 31, 2017, and the related notes to the financial statements, the respective changes in financial position thereof and the respective budgetary comparisons for the General Corporate Fund and the Retirement Fund for the year then ended, which collectively comprise the District's basic financial statements as listed in the table of contents.
Management's Responsibility for the Financial Statements
Management is responsible for the preparation and fair presentation of these financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.
Auditor's Responsibility
Our responsibility is to express opinions on these financial statements based on our audit. We did not audit the financial statements of the Metropolitan Water Reclamation District Pension Trust Fund (Pension Fund), which represents 83 percent and 76 percent, respectively, of the assets and revenues/additions of the aggregate remaining fund information. Those statements were audited by other auditors, whose report has been furnished to us, and our opinion, insofar as it relates to the amounts included for the Pension Fund, is based solely on the report of the other auditors. We conducted our audit in accordance with auditing standards generally accepted in the United States of America and the standards applicable to financial audits contained in Government Auditing Standards, issued by the Comptroller General ofthe United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.
An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor's judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity's preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity's internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.
We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinions.

Management's Discussion and Analysis (MD&A) - Unaudited
Year ended December 31, 2017 Metropolitan Water Reclamation District of Greater Chicago

The Metropolitan Water Reclamation District of Greater Chicago (the "District") is providing Management's Discussion and Analysis (MD&A) to assist the readers in understanding the financial information presented in this report. The MD&A includes a discussion ofthe basic financial statements and their relationship to each other. It also offers an analysis of the District's financial activities at both the government-wide and fund levels, based on known facts, and compares the current year's results with the prior year's. A budgetary analysis ofthe District's General Corporate Fund is provided, as well as an analysis of capital assets and debt activity. Finally, the MD&A concludes with a discussion of issues that are expected to be significant to the District's finances.
The MD&A should be read in conjunction with the Clerk/Director of Finance's letter of transmittal and the basic financial statements.

2017 FINANCIAL HIGHLIGHTS
The District's government-wide net position is $4,616,429,000. This can be attributed to the District's positive balance of 54,710,123,000 in net investment in capital assets.
The District's government-wide net position increased by $76,484,000 and is mostly attributable to the net effect of the increased investment in capital, adding approximately SI 18 million in capital assets offset by the spending of available bond proceeds. In addition, the District had increased tax revenues, interest on investments, grant revenue and a decrease in construction costs. These variances are explained further in the key financial comparisons section.
The District's combined fund balances for its governmental funds at December 31,2017 totaled $820,495,001, a decrease of $62,968,999 from the prior year. The decrease is primarily attributable to not issuing general obligation bonds in 2017 and a decrease in construction costs.
The District's government-wide liabilities increased by $55,532,999 in 2017 which is largely attributable to an increase in converted bond anticipation notes of approximately $30 million, an increase in the net pension liability of approximately $16 million, and a smaller increase in accounts payable and deferred revenue combined of approximately $6.2 million.

DISCUSSION OF THE BASIC FINANCIAL STATEMENTS
The District's basic financial statements include both a short and long-term view of its financial activities. The focus is on both the District as a whole (government-wide) and on major individual funds. The District's basic financial statements include three components: (1) government-wide financial statements; (2) fund financial statements; and (3) notes to the basic financial statements. In addition to the basic financial statements, the financial section of this report includes Required Supplementary Information (RSI) and Combining and Individual Fund Statements and Schedules.
Government-wide financial statements. The government-wide financial statements arc provided to give readers a long-term overview ofthe District's finances, similar to a private-sector business. Government-wide statements consist ofthe Statements of Net Position and Statements of Activities, and are prepared using the accrual basis of accounting and the economic resources (long-term) measurement focus. They include all the District's governmental activities; there are no business-type activities. The fiduciary funds' resources are restricted for employee pensions and other post-employment benefits, and are not available to support the operations ofthe District. Therefore, the fiduciary funds are not reported in the government-wide financial statements.
The Statements of Net Position report the financial position ofthe District as a whole, presenting all the assets and liabilities (including capital assets and long-term obligations) with the difference between the assets and deferred outflows of resources less liabilities and deferred inflows of resources representing net position. The increase or decrease

FINANCIAL SECTION 35

Management's Discussion and Analysis (MD&A) - Unaudited

in net position over time can serve as a useful indicator of whether the financial position ofthe District is improving or declining.
The Statements of Activities report the operating results ofthe District as a whole, presenting all revenues and expenses ofthe District as well as the change in net position. The Statements ofActivilies include revenues earned in the current fiscal year that will be received in future years, and expenses incurred for the current year that will be paid in future years (i.e. revenue for uncollected taxes and expenses for accumulated, but unused, compensated absences). Revenues are segregated as general revenues and program revenues. General revenues include taxes, interest on investments, and all other revenues not classified as program revenues. Program revenues include charges for services (i.e. user charges, land rentals, fees, forfeitures, and penalties) and capital giants. Depreciation for depreciable capital assets is recorded as an expense in this statement.
Fund financial statements. The District uses fund accounting to demonstrate compliance with finance-related legal requirements. For this purpose, a fund is a grouping of related accounts used to maintain control over resources segregated for specific activities or objectives.
The fund financial statements include infonnation segregated between the District's governmental funds and its fiduciary funds. The governmental funds are used to account for the day-to-day activities of the District, while the fiduciary funds account for employee pensions (Pension Trust Fund) and other post-employment benefits (OPEB Trust Fund). The Governmental Funds Balance Sheets and Statements ofGovemmental Fund Revenues, Expenditures and Changes in Fund Balances focus the reader's attention on the short-term financial position and results of operations, respectively, using the modified accrual basis of accounting. They also include budgetary statements for the General Corporate Fund and the Retirement Fund that compares the original and final budget amounts to actual results. This statement is provided to demonstrate compliance with the budget.
The Statements of Fiduciary Net Position and Statements of Changes in Fiduciary Net Position report the net position available for future pension and OPEB benefits and the change in net position, respectively. The fiduciary financial statements utilize the accrual basis of accounting, similar to that used for the government-wide financial statements.
Reconciliation of governmental fund financial statements to government-wide financial statements. Because the short-term focus of governmental fund financial statements is narrower than the long-term government-wide financial statement focus, reconciliations are required to explain the differences between the fund and government-wide financial statements. As a special purpose government, the District has elected to present the reconciliation by combining the presentation of the governmental fund statements with the government-wide statements. The Governmental Funds Balance Sheets are reconciled to the Statements of Net Position in a combined financial statement presentation (Exhibit A-O. Likewise, the Statements of Governmental Fund Revenues, Expenditures, and Changes in Fund Balances are reconciled to the Statements of Activities in a combined financial statement presentation (Exhibit A-2).
Notes to the basic financial statements. The basic financial statements include notes that provide additional disclosure to better explain the financial data provided in the basic financial statements.

KEY FINANCIAL COMPARISONS
Property taxes. The primary source of revenue for the District is ad valorem property taxes. All District funds, with the exception ofthe District's Capital Improvements Bond Fund, derive their revenues primarily from property taxes. In 2017, total tax revenues increased by SI 1,349.000 in the District's Statement of Activities, as shown on page 39. The property lax levies for the Corporate Fund was the only levy that decreased from prior year; however, the majority ofthe increase m property taxes recorded is due to the change in deferral of tax revenue affecting the ti mi ng of col lections.
Program revenue. T he other notable changes were in user charge revenue and land rentals. T he user charge revenue increase of $2,477,000, as shown on page 39. was primarily due to a new significant industrial user paying both 2016

Metropolitan Water Reclamation District of Greater Chicago

and 2017 user charges in 2017. User charge rales and remaining customers have not varied significantly from the prior year. The decrease of S2,814,000 in land rental revenue is due to a change in the rental revenue recognition policy in the current year where the District will defer all rental revenue based on current year payments if they cover the rental period for any time period subsequent to year end. The prior policy was to defer payments only for payments in the last 60 days of the year.
Construction costs. The decrease in construction costs of S50,668,000, shown on page 39, was due to fewer projects being classified as substantially complete in 2017. To be compliant with GASF3 34 reporting, the expense is reduced and the asset is increased when construction projects are capitalized. Thornton Reservoir was substantially complete in 2016. Although large construction projects continued throughout 2017, fewer were completed, thereby decreasing the construction costs for the current year.
Pension costs. The 2017 pension cost decreased $1,792,000 from 2016, as seen on page 39. The decrease can be attributed to changes in the pension expense due to GASB 68 additions and reductions to pension expense. Pension expense is made up of a variety of items including employee service cost, interest, benefit payments, administrative expenses and differences between expected and actual experiences. Employee contributions and net investment income of the fund offset some of these annual expenses.
Claims and judgments. The $5,886,000 increase on the Statement of Activities claims and judgments expense on page 39 is partly due to an increase in claims paid from the governmental funds of $2,119,000. The remainder ofthe expense is a result of the change in the claims liability.
Employee costs. The District's employee-related expenditures are the largest single cost of the General Corporate Fund, comprising 67.1% ofthe total outlays for 2017. Employee costs comprise regular pay, overtime, and health care benefits. The increase in employee costs of $2,166,845, shown on page 41, was attributable to an increase in salary and wages for existing employees and several budgeted positions being filled in 2017.
Energy costs. In 2017, energy costs in the General Corporate Fund showed an increase of $1,037,000 as seen on page 41. Energy costs are made up of electricity and natural gas. Both expenses increased in 2017. Natural gas increased approximately $533,000 as a result of a higher unit cost related to weather fluctuation, and an overall decrease in digester gas production at the Calumet Water Reclamation Plant. The remainder of the increase in energy cost was due to an increase in electricity use from increased aeration blower run time, which is part ofthe sewage treatment process, and resulting expenses.

Management's Discussion and Analysis (MD&A) - Unaudited
Year ended December 31, 2017

In 2017, General Corporate Fund expenditures totaled $344,050,000, an increase of SI,646,000, or 0.5%, from 2016. Employee costs, energy costs, and solids and waste disposal were the three largest expenditure components ofthe General Corporate Fund in 2017, accounting for 82.5% of total expenditures versus 81.6% in 2016. The major variances in expenses are explained under "Key Financial Comparisons" on pages 36-37.
Other Major Funds. The District's Debt Service Fund accounts for property tax revenues and interest earnings used for the payment of principal and interest on bonded debt. The Debt Service Fund's fund balance at the end of the current fiscal year totaled $147,000,000. The fund balance represented 64.2% of the total Debt Service Fund expenditures. The fund balance for the Debt Service Fund decreased by $ 16,508,000 in the current year, as a result of the decrease in property tax revenue and a slight increase in bond principal and interest payments.
The Capital Improvements Bond Fund is a capital projects fund used by the District for the construction and preservation of capital facilities. The Capital Improvements Bond Fund's resources are bond proceeds, government grants, and state revolving fund loans. The fund balance in the Capital Improvements Bond Fund at the end ofthe current fiscal year totaled $311,997,000. This amount will provide resources for the 2018 capital construction program. The fund balance represented 127.3% ofthe fund's expenditures. The fund balance decrease of $62,038,000 in the current year was primarily due to continued construction of capital projects and no issuance of general obligation bonds in 2017.
The Retirement Fund is classified as a major fund because total liabilities in prior years have been greater than 10% ofthe total governmental funds and the fund is used for collection ofthe tax levy which is remitted to the Pension Board. This presentation remains for comparative purposes. There is no fund balance for the Retirement Fund at the end ofthe current fiscal year, as all funds are transferred, or due to, the District's Pension Fund.

Properly taxes and personal property replacement taxes were $ 11,639,000 more than the budget, mostly due to the collection of taxes greater than the allowance. User charge receipts were $6,252,000 more than budgeted due to an additional $5.6 million dollar unbudgeted payment from a new significant industrial user paying both 2016 and 201 7 user charges in 201 7.

rate. Land rentals were SI ,628,000 more than the budget due to a continued effort to maximize the District's real estate portfolio. i
The 2017 General Corporate Fund final appropriation of 5399,541,000 remained equal to the original amount. Actual budgetary expenditures totaled $345,329,000, or 85.8%. of the total appropriation. The $54,212,000 excess of appropriations over actual expenditures was primarily due to claims and judgments costs being $23,712,000 less than appropriations, and positive variances in expenditures from all departments, most noticeably a 510,469,000 positive variance for Maintenance and Operations. Expenditures for the Maintenance and Operations Department were below appropriations, for reasons that include position vacancies throughout the year, lower than estimated use of chemicals due to refining the processes in phosphorous removal at Stickney, disin lection at Calumet, as well as lower than estimated distribution of biosolids to privately owned agricultural land.
The District's Reserve Claim fund actual payments were significantly lower than budgeted, resulting in a large variance between budget and actual, as it is the policy ofthe District to appropriate the entire Reserve Claim fund balance. This is consistent with the Board of Commissioners' policy to accumulate sufficient reserves for payment of future claims without exposing the District to financial risk that could curtail normal operations.
CAPITAL ASSETS AND MODIFIED APPROACH
Capital Assets. The District's reportable capital assets, net of accumulated depreciation, as of December 31, 2017, amounted to $7,594,442,000. Reportable capital assets, net of accumulated depreciation, for 2017 as compared to 2016 are as follows (in thousands of dollars):

Significant capital asset changes during the current fiscal year included the following:
Total capital asset additions exceeded retirements and depreciation by 5167.508.000 in 201 7.
Construction in progress increased by $137,743,000 from 2016 ro 2017 because several large projects continued through 2017 but were not completed, and therefore not moved to infrastructure. Major projects which remained in progress during 2017 include: additional construction related to Phase II ofthe McCook reservoir and surrounding tunnels, construction of primary settling tanks with an aerated grit facility, construction of the Addison Creek reservoir, continued construction of Stickncy's Phosphorous Recovery system, and construction of Calumet TARP screens.
Increase in the Modified Infrastructure is primarily due to the substantial completion ofthe distributed control system for solids processing at Stickney WRP, Mainstream Pumping Station and other remote stations. Completion of this project accounted for approximately $35 million of the increase to Infrastructure. T he remainder ofthe increase is due to the residual costs of construction projects completed in the prior year being added directlv to infrastructure.

In addition to the above, commitments totaling 5290.252,000 remain outstanding for ongoing construction projects. Additional disclosure on construction commitments can be found in Note 9 to the basic financial statements.
Modified approach. The District's infrastructure assets include interceptor sewers, wastewater treatment basins, waterway assets (such as reservoirs and aeration stations) and deep tunnels, drop shafts and regulating elements making up a pollution and flood control program called TARP. The District is using the modified approach to report its infrastructure assets, with the exception ofthe TARP deep tunnels and drop shafts, which arc depreciated. The District elected the modified approach to: a) clearly convey to the taxpayers the District's efforts to maintain infrastructure assets at or above an established condition level; b) provide and codify a process to coordinate construction projects between the Engineering and Maintenance and Operations departments; c) readily highlight infrastructure assets that need significant repair/rehabilitation/replacement under a construction project; and d) provide additional evaluative information to bond rating agencies to insure that the District's bond rating is maintained at the highest level.
The Kirie, Hanover, Egan, Central (Stickney), O'Brien, Calumet, Lemont, and Waterways network assets had their initial condition assessments completed between 2002 and 2006. Kirie, Central (Stickney) and Waterways each had its most recent condition assessment completed in 2017. The Egan and O'Brien networks each had its most recent condition assessment completed in 2016. The Hanover, Calumet and Lemont networks each had its most recent condition assessment completed in 2015. (See further discussion ofthe modified approach in the Required Supplementary Information Section). '
As noted in the Required Supplementary Information, the condition ratings for eligible infrastructure assets compare favorably with the District's target level of acceptable or bettor. In addition, there arc no significant differences between the estimated maintenance and preservation costs and the actual costs. Additional disclosure on the District's capital assets and modified approach can be found in the Notes 1.1. and 6 lo the basic financial statements and in the Required Supplementary Information section.
DEBT ACTIVITY
Long-term Debt. The District's long-term liabilities as of December 3 1,2017, totaled 54,359,376,000. The breakdown of this debt and changes from 2016 to 2017 are as follows (in thousands of dollars):

Significant changes in long-term liabilities during the current fiscal year included the following:
Bonds payable, net. decreased by 585,367,000 in 2017 as a result of payments on existing bonds with no additional issuances in the current year.
Bond anticipation notes increased by 5139,139,000 in 2017 as a result ofthe issuance of 5228,781,000 in notes and the conversion of $39.281.000 from bond anticipation notes to bonds plus an approximate $50 million chaime in interest accrued. .

FINANCIAL SECTION 45

Management's Discussion and Analysis (MD&A) - Unaudited
Year ended December 31, 2017
Claims payable decreased by $9,567,000 due to reductions in workers' compensation, general, health and dental, and environmental remediation claims.
A number of items factor into the Net Pension Liability. The $6,453,000 increase is the net change of increases in interest, service cost, administrative costs, and expected v. actual experience with decreases in contributions and net investment income. See Note 7 for additional details.
The District's general obligation bonds have the following long-term credit ratings: Standard & Poor's Financial Services. LLC AA+ Fitch, Inc. AAA Moody's Investors Service Aa2
In July 2015, Moody's Investor Service downgraded the District's bond rating from Aal to Aa2. In May 2016, Standard & Poor's Financial Services downgraded the District's bond rating from AAA to AA+. The primary reason for the downgrades is the pressure on the District's tax base due to the significant debt burden and pension liabilities for major governmental agencies in Cook County, reflecting the opinion on the affordability of possible tax increases by other agencies and how this could impact Cook County residents. Additional disclosure on debt can be found in Note 11 to the basicfinancial statements.
Debt Limits and Borrowing Authority. Various applicable sections ofthe Illinois Compiled Statutes establish the following limitations relative to the District's debt:
Effective October 1, 1997, the District may fund up to 100% ofthe aggregate total ofthe estimated amount of taxes levied or to be levied for corporate purposes, plus the General Corporate Fund portion of the personal property replacement tax, through borrowing from the Corporate Working Cash Fund and issuance of tax anticipation notes or warrants. The policy of the District currently is to fund up to 95%. The provisions also pertain to the Construction, Construction Working Cash, Stormwater Management, and Stormwater Working Cash Funds.
The amount ofthe District's debt may not exceed 5.75% ofthe last published equalized assessed valuation of taxable real estate within the District, which was SI40,752,201,000 for the 2016 property tax levy. At December 31, 2017, the District's statutory debt limit of $8,093,25 1,000 exceeded the applicable net debt amount of $2,963,366,188 by $5,129,884,812.
The Illinois Compiled Statutes provide authorization for the funding ofthe District Capital Improvement Program by the issuance of non-referendum capital improvement bonds. Starting in 2003, bonds may be issued during any budget year in an amount not to exceed $150 million plus the amount of any bonds authorized and unissued during the three preceding budget years. The District has issued various series of bonds since the authorization. This limitation is not applicable to refunding bonds, money received from the Water Pollution Control Revolving Fund, and obligations issued as part ofthe American Recovery and Reinvestment Act of 2009, issued prior to January I, 2011, commonly known as "Build America Bonds". Bonds authorized, unissued and carried forward were $450,000,000 for the budget year ended December 31, 201 7.
The District has non-referendum bonding authority until the year 2024. When the Property Tax Extension Limitation Law was made applicable to Cook County, the legislature recognized that the completion ofthe Tunnel and Reservoir Plan (TARP) was such a high priority that it exempted TARP bonds from tax cap limits. In 2010, the Local Government Debt Reform Act was amended. The District's debt service extension base for the levy year 2017 is S166,066,470 (the "Debt Service Extension Base"), which can be increased each year by the lesser of 5% or the percentage increase in the Consumer Price Index (as defined in the Limitation Law). Tho Property Tax Extension Limitation Law has been amended so that the issuance of bonds by the District to construct TARP will not reduce the District's ability to issue limited bonds for other major capital projects. The amount of outstanding non-referendum Capital Improvement Bonds may not exceed .3.35% of the last known equalized assessed valuation of taxable property within the District. Al

Additional information on the District's debt can be found in Note 11 to the basic financial statements and Exhibits I-10 through 1-12 of the Statistical Section.
ECONOMY AND OTHER CONDITIONS IMPACTING THE DISTRICT
The equalized assessed valuation ofthe District has experienced a 0.24% average growth rale over the last ten years although the 2016 equalized assessed valuation of $140,752,201 is 8% higher than the previous year. As in 2016, home sales seem slow, but area home prices continued to climb because there is insufficient inventory to meet the current demand. The median price of homes in the Chicago area was up 5.6% compared to the prior year. A strong fund balance, along with an emphasis on controlling expenditures, should allow the District lo protect its operations from economically sensitive revenues stemming from fiscal constraints at the federal and state levels. T he boundaries of the District encompass 91% ofthe land area of Cook County. The District is located in one ofthe strongest and most economically diverse geographical areas of Illinois. Unemployment for the Chicago-Naperville-Joliet Metropolitan Division decreased to a seasonally adjusted rale of 4.8% for 2017, down from 5.8% a year earlier. Employment, tourism, manufacturing, and the commercial and residential real estate markets have all been steadily improving in the past few years.
Corporate Fund. T he Corporate Fund is the District's general operating fund and includes appropriation requests for all the day-to-day operational costs anticipated for 2018. The total appropriation for the Corporate Fund in 2018 is $370.2 million, an increase of $ 1.3 million, or .3% from the 2017 Adjusted Budget. The 201 8 tax levy for the Corporate Fund is $223.9 million, an increase ol"SI6.5 million or 7.4% compared to the 2017 Adjusted Budget.



FINANCIAL SECTION 47

Year ended December 31, 2017

Property taxes and user charges are the primary funding sources for the District's Corporate f und. Illinois law limits the tax rate of this fund to 41 cents per $100 of equalized assessed valuation. The estimated tax rate for the Corporate Fund in 2018 is 16.11 cents, an increase of 0.66 cents from 2017 as adjusted. User charges are collected from industrial, commercial, and non-profit organizations to recover operations, maintenance, and replacement costs proportional to their sewage discharges, in excess of properly taxes collected. The major categories of payers: chemical manufacturers, food processors, and government services, are generally expected to maintain their recent level of discharges.
Stormwater Management Fund. The Stormwater Management Fund was established by Public Act 93-1049 on January 1, 2005. This fund accounts for tax levies and other revenue to be used for stormwater management activities throughout all of Cook County, including areas that currently lie outside the District's boundaries. The fund consolidates the stormwater management activities ofthe Engineering and Maintenance & Operations Departments.
The Stormwater Management Fund appropriation for 2018 totals $65.6 million, an increase of SI 9.8 million or 43.2% from the 2017 Adj listed Budget. Property taxes are the primary funding source for the District's Storm water Management Fund. Illinois law limits the tax rate of this fund to 5 cents per $100 of equalized assessed valuation. The estimated tax rate for the Stormwater Management Fund in 2018 is 3.2 cents, which is an increase of 0.4 cents from 2017 as adjusted.
Although the primary funding source for the Fund is the Stormwater Property Tax Levy, the District also issued Alternate Revenue Bonds funded from the Slormwatcr Levy in both the 2015 and 2016 bond offerings. The "green" projects financed by the bonds involves the development, design, planning and construction of regional and local stormwater facilities provided for in the countywidc stormwaler management plan and the acquisition of real property.
By means of this program, the District has completed Detailed Watershed Plans (DWP) for all six watersheds in Cook County, initiated a Stormwater Management Capital Improvement program, initiated a Small Streams Maintenance Program (SSMP), and adopted and implemented the Watershed Management Ordinance.
Two categories have been established for DWP projects. The lirst category is streambank stabilization, which involves addressing critical active streambank erosion threatening public safety, structures, and/or infrastructure. The second category of projects addresses regional overbank flooding. The selected projects constitute the Stormwater Capital Improvement Program, and will be scheduled according to funding availability.
Through the management ofthe SSMP, the M&O Department works to reduce Hooding in urbanized areas. The streams that flow through the neighborhoods of Cook County are more than just a scenic part ofthe landscape but also serve the vital function of draining stormwater and preventing flooding. In order to function, the streams must be maintained, which includes removing blockages and preventing future blockages by removing dead and unhealthy trees and invasive species.

Metropolitan Water Reclamation District of Greater Chicago

The District's statutory authority lor Stormwater Management in Cook County (70 ILCS 2605/7h) was amended in 2014 to allow for the acquisition of flood-prone properties. Subsequent to amending the Cook County Stormwater Management Plan to be consistent with Public Act 98-0652, the District's Board of Commissioners adopted a policy on selection and prioritization of projects for acquiring flood-prone property, which is comprised of three distinct components, as follows:
Local Sponsorship Assistance Program: The District's top priority will be to facilitate the Illinois Emergency Management Agency's federally funded program by assisting local sponsor communities in providing their share of the cost for property acquisition;
District Initiated Program: The cost of a property acquisition alternative will be estimated for any approved project and compared to the estimated cost of the structural project determined through a preliminary engineering analysis. Should the cost of the property acquisition alternative be less than the structural project, and the benefits at least equivalent, the acquisition alternative will be pursued in lieu ofthe structural project;
Local Government Application Program: The District will consider applications directly from local governments requesting property acquisition of specific flood-prone structures.
Capital Improvement Program: Construction Fund and Capital Improvements Bond Fund. The District's overall Capital Program includes 2018 project awards, land acquisition, support, future projects, and projects under construction, with a total cost of approximately $1.2 billion. Capital projects involve the acquisition, improvement, replacement, remodeling, completing, altering, constructing, and enlarging of District facilities. Included are all fixtures which are permanently attached to and made a part of such structures and non-structural improvements, and which cannot be removed without, in some way, impairing the facility or structure.
Projects under construction have been presented and authorized in previous Budgets and are recognized in the Annual Budget as both outstanding liabilities in the Capital Improvements Bond Fund, and as re-appropriations in the Construction Fund. Future projects, not yet appropriated, are included in the Annual Budget to present a comprehensive picture of the District's Capital program. These future projects will be requested for appropriation subject to their priority, design, and available funding.
The District utilizes two funds for its Capital program, the Construction Fund and the Capital Improvements Bond Fund. The Construction Fund is utilized as a "pay as you go" capital rehabilitation and modernization program. Capital projects are financed by a tax levy sufficient to pay for project costs as they are constructed. As the District replaces, rehabilitates, and modernizes aged and less effective infrastructure, capital projects are assigned to the Corporate, Construction, or Capital Improvements Bond Fund based on the nature ofthe project, dollar magnitude, and useful life of the improvement. The Construction Fund is used for operations-related projects, where the useful life of the improvement is less than 20 years.
The Capital Improvements Bond Fund, the District's other capital fund, includes major capital infrastructure projects whose useful lives extend beyond 20 years, and which will be financed by long-term debt. Federal and State grants, and State Revolving Fund loans.
The 1995 Tax Extension Limitation Law (Tax Cap), and subsequent amendments lo the bill, dramatically impacted the methods of financing the Capital Improvements Bond Fund. The original legislation required, in general, that all new debt be approved by referendum. However, an exemption for projects initiated before October 1, 1991 was granted to the District to enable completion ofthe Tunnel and Reservoir Plan (TARP).- The bill was later amended lo establish a "debt extension base," which allowed local governments, with non-refcrendum authority, to continue to issue non-referendum debt in terms of "limited bonds'' as long as their annual debt service levies did not exceed 1994 levels. This law was further amended in 1997 to exclude TARP project debt from this debt service extension base. The passage of legislation in 1997 allowing for expanded authority to issue "limited bonds" by excluding pre-existing TARP projects provides additional financing flexibility to proceed with our Capital program.

Year ended December 31, 2017

The USEPA implemented the State Revolving Fund (SRF) to ensure that each state's program is designed and operated to continue to provide capital funding assistance for water pollution control activities in perpetuity, but preserves a high degree of flexibility for operating revolving funds in accordance with each state's unique needs and circumstances. Funds in the SRF are not used to provide grants, but must be available to provide loans for the construction of publicly owned wastewater treatment works. Low interest SRF loans arc an integral part ofthe District's capital improvements financing. SRF revenues are based on the award and construction schedule of specific projects. In 2017, the District received $228,781,500 in cash receipts for SRF projects.
Construction Fund. The Construction fund appropriation for 2018 totals $26,080,600, a decrease of $8,369,800 or 24.3% from the 2017 Adjusted Budget.
Capital projects in the Construction Fund arc primarily supported by property taxes and thus subject to the Tax Cap. The 2018 tax levy planned for the Construction Fund is $11.700,000. a decrease of S4.6 million or 28.1% from the 2017 Adjusted Levy.
Capital Improvements Bond Fund. The 2018 appropriation for the Capital Improvements Bond Fund is $312,982,900, a decrease of $41,642,700 or 11.7% from the 2017 Adjusted Budget. Capital projects pursued by the District are: mission critical, improve environmental quality, preservation/rehabilitation of existing infrastructure or commitment to the community through process optimization. The appropriation is based on the scheduled award of $275,206,000 in projects. Capital Improvements Bond Fund projects scheduled for award in 2018 with estimated award values include one TARP modification project of $2.5 million; eleven plant expansion and improvement projects at $38.6 million; and fourteen facilities replacement projects at $89.1 million.
The decrease in appropriation for the Capital Improvements Bond Fund of $41,642,700 reflects the pattern in the award of major projects. An appropriation for the open value of existing contracts is also carried forward from the prior year.
The remaining $37,776,900 million appropriation fortius fund will provide for studies, services, and supplies to support District design and administration of proposed and ongoing construction activity, including the TARP reservoirs. A comprehensive narrative, and exhibits detailing our entire Capital program, is provided in the Capital Budget (Section V) ofthe 2018 budget document.
A listing and description of proposed projects, and projects under construction, scheduled for 2018, can be found in the Capital Budget.(Scction V) ofthe 2018 Budget document.
Other Post-Employment Benefits (OPEB) Trust. The District provides subsidized health care benefits for its retirees. The Governmental Accounting Standards Board (GASB) Pronouncement 45 requires reporting ofthe future liability for maintaining these benefits in the Comprehensive Annual Financial Report (CAFR).
In 2006, the District proposed state legislation to give authority to establish an OPEB trust. Public Act 95-394 became effective on August 23, 2007. Since inception, the District has budgeted and transferred a total of $ 127,400,000 million into the OPEB Trust Fund. The District has continued to contribute $5.0 million per year until the T rust is fully funded. Total net position was $195,200,000 as of December 31, 2017. The accumulated unfunded OPEB obligation was estimated at approximately S113,547,457 at December 3 1.201 7. On December 19. 2013, the Board of Commissioners adopted a revised investment policy statement for the Metropolitan Water Reclamation District Retiree Health Care Trust.







50 FINANCIAL SECTION

Metropolitan Water Reclamation District of Greater Chicago

In 2007, the Board adopted an initial advance funding policy meant to (i) improve the District's financial position by reducing the amount of future contributions and (ii) serve to establish a reserve to help ensure the financial ability to provide healthcare coverage for District retirees and annuitants in the future. On October 2, 2014, the advance funding policy was amended by the Board with the following guidelines:

Target Funding Level: 100% maximum
Funding Period: 12 years
Funding Amount: $5 million funding in each of the twelve years 2015 through 2026, with no further advance funding contribution required after 2026

Beginning in 2027, cash to be withdrawn from the Trust to fund claims and insurance premiums will be determined by the Trust's actuary with the target funding level to be maintained at 100% for all future years. There is currently no legal requirement for the District to partially or fully fund the OPEB Trust Fund and any funding is on a voluntary basis.
The policy adopted by the District is cautious by design, and will provide ample opportunity for ad justment as experience is gained. Future direction may also be changed significantly by national health care policies and programs.
Pension and OPEB Reporting Changes. The District implemented GASB 68, Accounting and Financial Reporting for Pensions, beginning with the year ended December 3 I, 2015. The implementation of this standard resulted in a net pension liability recognized by the District of S947,300,000; however, net position remained positive. The OPEB Trust Fund implemented GASB 74 (for post-retirement plan) in 201 7 and the District will be implementing GASB 75 (for employer) in 2018.
Organized Labor. The District has seven collective bargaining agreements that cover sixteen unions and include approximately 770 ofthe District's employees for the purposes of establishing wages and benefits. Three-year successor agreements were negotiated with all bargaining units in 2017 and will expire in 2020.
Retirement Fund. On August 3, 2012, Governor Quinn signed House Bill 4513, now Public Act 97-0894, into law. The tax multiple, which is limited by state statute, was increased in 2013 from 2.19 lo the amount sufficient lo meet the Fund's actuarially determined contribution requirement, but not to exceed an amount equal to 4.19 times the employee contributions two years prior. The employee contributions for tier I employees (those hired before January 1. 2011) increased 1% each year for 3 years beginning January 1, 2013, increasing the contribution rate from 9% to 12%. The employee contributions will remain at 12% until the funded ratio reaches 90% then the contribution rate will be reduced to 9%.

1. Summary of Significant Accounting Policies
The significant accounting policies ofthe Metropolitan Water Reclamation District of Greater Chicago (District) conform to generally accepted accounting principles (GAAP) in the United States of America as applicable to governmental units and are described below.
Financial Reporting Entity - The District is a municipal corporation governed by an elected nine-member Board of Commissioners. As required by GAAP, these financial statements present the District (the primary government) and its component units, the Metropolitan Water Reclamation District Retirement Fund (Pension Trust Fund - Note 7) and the Metropolitan Water Reclamation District Retiree Health Care Trust Fund (OPEB Trust Fund - Note 8). The Board of Trustees for the Pension Trust Fund is composed of seven members. Two of these Trustees are Commissioners appointed by the Board of Commissioners ofthe District, four are District employees elected by members of the fund and one is a retired employee of the District. Although the Pension Trust Fund and OPEB Trust Fund are legally separate entities, for which the primary government is not financially accountable, they arc included in the District's basic financial statements as fiduciary funds. The nature and significance of the Pension Trust Fund and OPEB Trust Fund's relationship with the primary government is such that exclusion would render the District's financial statements incomplete or misleading. Complete financial statements of the Pension Trust Fund can be obtained from their administrative office at 111 East Erie Street, Chicago, Illinois, 60611-2898 or on their website: mwrdrf.org . Complete financial statements ofthe OPEB Trust Fund can be obtained from the Treasurer ofthe Metropolitan Water Reclamation District at 100 East Erie Street, Chicago, Illinois 60611-5498 or on the District's website: mwrd.org .
Government-wide and Fund Financial Statements - The District's basic financial statements include government-wide financial statements and fund financial statements.
The government-wide financial statements include the Statements of Net Position and the Statements of Activities, and contain information for all the District's governmental activities but exclude the Pension Trust Fund and the OPEB Trust Fund, fiduciary funds whose resources are not available to finance the District's operations. The effect of interfund transactions has been removed from the government-wide statements. The Statements of Net Position report the financial condition ofthe District. This statement includes all existing resources and obligations, both current and non-current, with the difference between the two reported as net position. The Statements of Activities report the District's operating results for the year with the difference between expenses and revenues representing the changes in net position. Expenses are reported by department while revenues are segregated by program revenues and general revenues. Program revenues contain charges forservices including user charges, land rentals, fees, forfeitures, penalties and capital grants. General revenues include taxes, interest on investments, and all other revenues not classified as program revenues.
In government, the basic accounting and reporting entity is a "fund." A fund is defined as an independent fiscal and accounting entity, with a self-balancing set of accounts which record financial resources, together with all related liabilities, obligations, reserves, and equities, which arc segregated for the purpose of carrying on specific activities or attaining certain objectives, in accordance with special regulations, restrictions or limitations. Separate fund financial statements arc included in the basic financial statements for the major governmental funds. The emphasis ofthe governmental fund financial statements is on major funds, with each major fund displayed as a separate column. The governmental fund financial statements include a budgetary statement for the General Corporate Fund and the Retirement Fund.
As a special purpose government, the District has elected lo make a combined presentation of the governmental fund statements and the government-wide statements, therefore, the basic financial statements include combined Governmental Funds Balance Sheets/Statements of Net Position (Exhibit A-l) and combined Statements of Governmental Fund Revenues, Expenditures, and Changes in Fund Balances/Statements of Activities (Exhibit A-2). Individual line items of the governmental fund financials are reconciled to government-wide financials in a separate column on the combined presentations, with in-depth explanations offered in Note 2.

The District reports the following major governmental funds: General Corporate Fund
The fund was established to account for an annual property tax levy, and certain other revenues, which are to be used for the payments of general expenditures ofthe District not specifically chargeable to other funds. Included in this fund are accounts maintained by the District restricted to making temporary loans to the Corporate Fund. These accounts were established under Chapter 70, ILCS 2605/9b ofthe Illinois Compiled Statutes, which refers to these accounts as a "Working Cash Fund."

Metropolitan Water Reclamation District of Greater Chicago
Basis of Accounting and Measurement Focus Government-wide and Fiduciary Fund Financial Statements
The government-wide and fiduciary financial statements arc reported using the economic resources measurement focus and the accrual basis of accounting. Revenues are recorded when earned and expenses are recorded at the time liabilities are incurred, regardless ofthe period of related cash flows. Property taxes are recognized in the year of levy and personal property replacement taxes are recognized in the year canted. Grants and similar items are recognized as revenue in the fiscal year that all eligibility requirements have been met.
Governmental Fund Financial Statements
The District's governmental funds are reported using the current financial resources measurement focus and the modified accrual basis of accounting. Under the modified accrual basis, revenues are recognized when they become measurable and available to finance operations. Expenditures are recognized in the period in which the fund liability is incurred except for principal and interest on long-term debt, compensated absences, claims, judgments, and arbitrage, which are recognized when due and payable.
The accounting and reporting treatment applied to the capital assets and long-term liabilities associated with a fund are determined by its measurement focus. Since governmental funds arc accounted for on the current financial resources measurement focus, only current assets and current liabilities are included on their balance sheets. Their reported fund balance (net current assets) is considered a measure of "available spendable resources." Governmental fund operating statements present increases (revenues and other financing sources) and decreases (expenditures and other financing uses) in net current assets. Accordingly, they are said to present a summary of sources and uses of "available spendable resources" during a period.
Property taxes, user charge revenue, interest, land rentals, and personal property replacement lax revenue are susceptible to accrual. In general, the revenue recognition period is limited to amounts collected during the period or within sixty days following year-end. Revenues that are unavailable are reported as deferred inllows of resources.
Grants from federal and State agencies are recorded as revenues in the fund financial statements when reimbursable expenditures are incurred, or other eligibility requirements imposed by the provider arc met, and the grant resources are measurable and available.
Property taxes attach as an enforceable lien on property as of January 1 ofthe levy year. They are levied and recorded as a receivable as of January 1 and are due in two installments in the following year. T he annual ordinance for the levy of taxes contains a reserve for loss in collection of taxes. The District reviews the reserve annually.
Budgeting (appropriations) - The District's fiscal year begins January I and ends on December 3 I. The District's procedure for adopting the annual budget consists ofthe following stages:

After the first half of the fiscal year, the Budget Office holds a meeting with departmental budget representatives to discuss policy and procedures for budget preparation that begins in July. Instructions are distributed to departments, together with guidelines from the Executive Director, which indicate the direction the Budget should follow for the coming fiscal year. The basic forms are returned to the Budget Office and a general summary is prepared for the Executive Director, who conducts departmental hearings in August.
The public budget process begins with Board of Commissioners Study Sessions providing a budget overview in June.

FINANCIAL SECTION 71

Notes to the Basic Financial Statements
" Year ended December 31, 2017
A revenue meeting is conducted by the Executive Director, Administrative Services Officer, and Budget Officer, along with those departments responsible for revenue items. Available resources used to finance the Budget are analyzed at this meeting.
When departmental estimates arc approved and final decisions are made, a Budget Message is prepared and the proposals ofthe Executive Director become the initial budget document. After departmental requests are finalized, the Executive Director's Budget Recommendations are published within 15 days. The Executive Director's Budget Recommendations arc published and presented lo the Board in October. At all times, the Budget figures are balanced between revenues and expenditures.
The Board's Committee on Budget and Employment holds public meetings with the Executive Director and department heads regarding the Executive Director's proposals.
At the conclusion of these hearings, the Committee on Budget and Employment recommends the preparation of a second document, a supplement to the Executive Director's Budget .Recommendations called the "Tentative Budget," which incotporates changes approved at the hearings. Once printed, this is placed on public display, along with the Executive Director's Budget Recommendations, for a minimum of 10 days. An advertisement is published in a general circulation newspaper announcing the availability ofthe Tentative Budget for inspection at the main office ofthe District, and specifying the time and dale ofthe public hearing.
At least one public hearing is held between 10 and 20 days after the Budget has been made available for public inspection. All interested individuals and groups are invited to participate.
After the public hearing, the Committee on Budget and Employment presents the Tentative Budget, which includes revisions and the approved Appropriation and Tax Levy Ordinances, to the Board for adoption. This action must lake place before January 1.
The Budget, as adopted by the Board, can be amended once at the next Regular Meeting of the Board. No amendment, however, can be requested before a minimum of five days after the Budget has been adopted. Amendments for contracts and/or services not received before December 31 must be re-appropriated in the new Budget and are included through this amendment process.
The final budget document "As Adopted and Amended" is produced, and an abbreviated version, known as the "short form" is published in a newspaper of general circulation before January 20 ofthe fiscal year.
Budget implementation begins on January 1. The Finance Department and Budget Office provide control of appropriations and ensure that all expenditures are made in accordance with budget specifications. The manual entitled "Budget Code Book" is published in conformance with the Adopted Budget and is used lo administer, control, and account for the Budget.
Supplemental appropriations can be made for the appropriation of revenues from federal or state grants, loans, bond issues, and emergencies. The Executive Director is authorized to transfer appropriations between line items within an object class of expenditure within a department. After March I of each fiscal year, transfers of appropriations between objects of expenditures or between departments must be presented for approval to the Board in accordance with applicable statutes.
(l.3)The Board can authorize, by a two-thirds majority, the transfer of accumulated investment income between funds and the transfer of assets among the Working Cash Funds.




72 FINANCIAL SECTION

Metropolitan Water Reclamation District of Greater Chicago
Deposits with escrow agent in the amount of 5280,000 arc currently held with the District's workman's compensation third party provider, all others (if any) represent cash with the escrow agent for the subsequent payment of interest on debt.
Certificates of deposit arc stated at cost plus accrued interest.
Investments of the Governmental Funds are reported at fair value plus accrued interest. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants at the measurement date. Changes in the carrying value of investments, resulting in realized and unrealized gains or losses, arc reported as a component of investment income in the statement of revenues, expenses and changes in fund balances.
Investment securities, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term that could materially affect the amounts reported in the statement of net position and in the statement of revenues, expenses and changes in fund balances.
The investment with the State Treasurer's Illinois Funds is measured at the net asset value per share provided by the pool. The Illinois Funds are not registered with the SEC. State statute requires the State Treasurer's Illinois Funds to comply with the Illinois Public Funds Investment Act (30 IECS 235). Oversight is provided by the State Treasurer. Investments ofthe Pension and OPEB Trust Funds, other than short-term investments, are also stated at fair value.
Inventory, consisting mainly of materials, supplies, and repair parts which maintain and extend the life of the District's Treatment facilities, is reported on the Balance Sheet of the General Corporate Fund and the government-wide Statements of Net Position. The District maintains a perpetual record-keeping system and uses a moving-average method, based on cost, for pricing its storeroom inventories. Materials, supplies, and repair parts arc recorded as expenditures/expenses when consumed.
i. Prepaid assets represent services the District has paid for but has not received the full benefit. Prepaids are
recorded as expenditures/expenses when consumed.
Inventory balances and prepaid insurance at year-end are reported as nonspendable fund balance in the governmental funds.
j. Restricted assets represent cash and investments set aside pursuant to real estate escrow and intergovernmental agreements.
k. Interfund transactions represent governmental fund transactions for the following: a) loans between funds reported as due to /due from other funds; b) reimbursements between funds reported in the fund financials as expenditures in the reimbursing fund and a corresponding reduction in expenditures in the reimbursed fund; and c) transfers between funds. All interfund transactions are eliminated in the government-wide financial statements. See Note 12 for further disclosure of interfund transactions.

Notes to the Basic Financial Statements
Year ended December 31, 2017


1. Capital Assets including land (and land improvements), buildings, equipment, computer software, infrastructure, acquired easements, and construction in progress are recorded at historical cost or estimated historical cost in the government-wide financial statements. Interest costs are not capitalized. Infrastructure assets include the District's sewers, water reclamation plants (WRP,) waterway assets, TARP deep tunnels, and drop shafts. The thresholds for reporting capital assets are as follows:
Land and buildings SI00,000 and over
Infrastructure $500,000 and over
Equipment $20,000 and over
Computer software $ 100,000 and over
Depreciation and amortization of capital assets is provided on the straight-line method (using a ten percent salvage value for equipment) over the following estimated useful lives:
Buildings and land improvements 80 years
Infrastructure (TARP deep tunnels and drop shafts only) 200 years
Equipment 6-50 years
Computer software 5 years
The District is using the modified approach as an alternative to depreciation to report its eligible infrastructure assets, with the exception ofthe TARP deep tunnels and drop shafts, which are depreciated. The modified infrastructure assets are categorized into networks, systems, and subsystems. Each ofthe District's seven WRPs represents a separate network and the waterway assets are an eighth network. The systems within the networks are categorized by the process flow through the network (i.e., collection system, treatment processes system, solids processing system, flood & pollution control system, or drying solids/utilization system). The subsystems represent the major processes of each system (e.g., fine screens and grit chambers arc subsystems ofthe treatment processes system). Condition assessments at each network are performed at the subsystem level and these assessments are compiled into a single assessment for each system. The rating scales used in the condition assessments are explained in the Required Supplementary Information immediately following the notes. Infrastructure assets reported under the modified approach are not depreciated, since the District manages these assets using an asset management system, and documents that the assets are being preserved at a level of acceptable or better, as evidenced by a condition assessment.
In compliance with Governmental Accounting Standards Board (GASB) Statement 34, existing infrastructure assets accounted for with the modified approach are not reported in the government-wide financial statements until an initial condition assessment is completed for the assets' network. Currently, all the District's WRPs infrastructure assets are reported as infrastructure under the modified approach in the govcrnmcnt-widc financial statements. Condition assessments of eligible infrastructure assets must be completed at least every three years following the initial assessments. The Kirie, Central (Stickney ), Hanover, O'Brien, Egan. Calumet, Lemont WRPs, and Waterways had their initial condition assessments completed between 2002 and 2006. The Kirie. Central (Stickney) and Waterways each had its most recent condition assessment completed in 2017. The Egan and O'Brien networks each had its most recent condition assessment completed in 2016.

vacation, holiday and overtime pay. Depending upon the date ofhire and/or collective bargaining agreements, employees may also be eligible to receive severance pay and 50% of accumulated sick pay up to a maximum of sixty days. Compensated absences are accrued as they arc earned in the government-wide financial statements. Expenditures and liabilities for compensated absences are recorded in the fund financial statements when due and payable. Included in the long-term liabilities ofthe Statements of Net Position at December 31, 2017, arc liabilities for compensated absences of $2,516,000, due within one year, and $22,811,000, due in more than one year.
n. Deferred Outflows/Inflows of Resources - Deferred inflow of resources is an acquisition of net position by the government that is applicable to a future period. Deferred outflow of resources is a consumption of net position by the government that is applicable to a future reporting period.
o. Long-Term Obligations - Long-term debt and other long-term obligations arc reported in the government-wide Statements of Net Position. Bond premiums are reported with bonds payable and amortized over the life of the bonds, which approximates the effective interest method, in the government-wide financial statements. In addition, the refunding transaction cost, representing the excess of the amount required to refund debt over the book value ofthe old debt, is reported as a deferred outflow of resources and amortized over the shorter ofthe life ofthe old debt or new debt in the govcrnmcnt-widc financial statements.
The face amounts ofthe debt and bond premiums arc recognized as other financing sources during the issuance period in the fund financial statements, while bond discounts arc reported as other financing uses. Issuance costs, whether or not withheld from the actual debt proceeds received, and refunding costs are recognized as debt service expenditures in the fund financial statements.
p. Fund Balances - The Board of Commissioners on December 9,2010, adopted a new fund balance classification policy in accordance with GASB Statement No. 54, Fund Balance Reporting and Governmental Fund Type Definitions: The policy categorizes the balances of governmental funds into the following categories: nonspendable, restricted, committed, assigned and unassigned fund balances. The categories are described as follows:
• Nonspendable Fund Balance - This consists of amounts that cannot be spent because they are either not in spendable form, or arc legally or contractually required to be maintained intact.
Restricted Fund Balance - Reported when constraints placed on the use of resources arc cither externally imposed by creditors, grantors, contributors, or laws or regulations of other governments; or imposed by law through constitutional provisions or enabling legislation.
Committed Fund Balance - This consists of amounts that can only be used for specific purposes pursuant to constraints imposed by a board motion. The District's commissioners shall establish, modify, or rescind a fund balance commitment by vote of a motion presented to the Board.
Assigned Fund Balances - This consists of amounts that arc constrained by the District's intent to be used for specific purposes, but arc neither restricted nor committed. The District's Board of Commissioners approved a motion authorizing the Executive Director to assign amounts of fund balances to a specific purpose. The District has an assigned fund balance of SI47,473,000 in the Capital Improvement Bond Fund, for future capital projects.
Unassigned Fund Balances - This classification represents fund balance that has not been restricted, committed, or assigned to specific purposes within the general fund.
In the General Corporate Fund, the District considers restricted amounts to have been spent first when an expenditure is incurred for purposes for which restricted fund balance is available, followed by committed

FINANCIAL SECTION 75

Notes to the Basic Financial Statements
Year ended December 31, 2017

amounts, and then assigned amounts. Unassigned amounts are used only after the other categories of fund balance have been fully utilized. In governmental funds other than the General Corporate Fund, the District considers restricted amounts to have been spent last. When an expenditure is incurred for purposes for which restricted fund balance is available, the District will first utilize assigned amounts, followed by committed amounts, and then restricted amounts.
q. Net Position - The government-wide Statements of Net Position display three components of net position, as follows:
Net investment in capital assets - This consists of capital assets, net of accumulated depreciation, less the outstanding balances of any debt attributable to capital assets (net of unspent bond proceeds).
Restricted Net Position - This consists of net position that is legally restricted by outside parties, or by law through constitutional provisions or enabling legislation. Net position restricted for working cash and reserve claims is based on legal restrictions, while net position restricted for debt service and capital projects is based on legal restrictions and/or outside parties. The government-wide statement of net position reports $700,839,000 of restricted net position.
Unrestricted Net Position - This consists of net position that does not meet the definition of "restricted" or "net investment in capital assets."
r. User Charge - The Environmental Protection Agency requires grant recipients to charge certain users of waste water treatment services a proportionate share of the cost of operations and maintenance. The District has utilized a User Charge System since January 1, 1980. The system was developed in accordance with 70 ILCS 2305/7.1.
s. Comparative Data and Reclassifications - The basic financial statements present comparative data for the prior year to provide an understanding ofthe changes in financial position and results of operations, but not at the level of detail required for presentation in accordance with accounting principles generally accepted in the United States of America.
t. Use of Estimates - The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, deferred outflows, liabilities and deferred inflows, disclosure of contingent assets and liabilities al the date ofthe financial statements and the reported amounts of revenues and expenditures/ expenses during the reported period. Actual results could differ from those estimates
u. New Accounting Pronouncement - The OPEB Trust implemented GASB 74, Financial Reporting For Postemployemcnt Benefit Plans Other Than Pension Plans. The District will be implementing statement GASB 75, Accounting and Financial Reporting For Poslemploymenl Benefits Oilier Than Pensions, in 2018.

Total fund balances of governmental funds S 820.495
Amounts reported for governmental activities in the Statements of Net Position are different because' Capital assets are not current financial resources and therefore arc not reported as assets in governmental funds. However, capital assets are reported in the Statements of Net Position. The cost of capital assets and accumulated depreciation is as follows:
Capital assets 7,891,314 Accumulated depreciation/amortization (296,872) Capital assets, net 7.594,442 Long-term liabilities are not due and payable in the current period and accordingly are not reported as liabilities in governmental funds.

Bond refunding transactions 4.S99
Total bond premium and refunding transactions (177.349)
Interest on debt is not accrued in governmental funds, but rather is recognized as a liability and an
expenditure when due Interest is recorded as a liability as it is incurred in the Statements of Net
Position. The 2017 amount is:
Accrued interest (15.899) Some assets reported in governmental funds do not increase fund balance because the assets arc not "available" to pay for current-period expenditures. These assets are offset by deferred inflow of resources in the governmental funds. However, these assets increase net position in the Statements of Net Position They consist of:
Deferred property taxes and personal property replacement tax 477,980
Grants and rents 944
Deferred inflows for other pension amounts (15.102)
Adjustment to deferred inflow of resources 463.822 Deferred outflows of resources represent items related to pension, which will be recognized as a pension expense m future reporting periods. Deferred outflows consist of employer contributions and "other" which includes differences between expected and actual experience, changes of assumptions, and net differences between projected and actual earnings on pension plan investments. However, these items arc reported in the Statement of Net Position. They consist of:
Deferred outflows for employer contributions subsequent to measurement dale 89.858

Net change in fund balances of governmental funds S (62,969)
Amounts reported for governmental activities in the Statements of Activities are different because.
Construction costs for capital outlays are reported as expenditures in governmental funds. However, in the Statements of Activities, the cost of capital assets is allocated over their estimated useful lives as depreciation expense except for those assets under the modified approach. In the current period, these amounts arc:
Construction costs and other capital outlays 182,962
Depreciation expense-allocated to various departments (3.128)
Depreciation/amortization expense-unallocated (12,063)
Excess of construction and capital outlay costs over depreciation expense 167,771
Debt proceeds provide current financial resources to governmental funds. However, issuing debt increases long-term liabilities in the Statements of Net Position. In the current period, debt proceeds and related items were:
Bond anticipation notes proceeds (175,245)
Repayment of long-term debt is reported as an expenditure in the governmental funds, or as an other financing use in the case of refunding, but the repayment reduces the long-term liabilities in the Statements of Net Position. In the current year, the repayments consist of:

Debt service principal retirement 1 13,695
Some expenses reported in the Statements of Activities do not require the use of current financial resources and therefore are not reported as expenditures in governmental funds. These activities consist of:
Change in compensated absences-allocated to various departments 1,675

Change in bond interest 246
Change in bond anticipation notes interest (3.175)

FINANCIAL SECTION 79

Notes to the Basic Financial Statements
Year ended December 31. 2017 Interest Rate Risk
The District's investment policy protects against fair value losses resulting from rising interest rates by structuring its investments so that sufficient securities mature to meet cash requirements, thereby avoiding the need to sell securities on the open market prior to maturity, except when such a sale is required by state statute. In addition, the District's policy limits direct investments to securities maturing in five (5) years or less. Written notification is required to be made to the Board of Commissioners ofthe intent to invest in securities maturing more than five (5) years from the date of purchase.
Credit Risk
The District's investment policy applies the "prudent person'' standard in managing its investment portfolio. As such, investments arc made with such judgment and care, under circumstances then prevailing, which persons of prudence, discretion and intelligence exercise in management of their own affairs, not for speculation, but for investment, considering the probable safety of their capital as well as the probable income to be derived. The District's investment policy limits investments in commercial paper to the highest rating classifications, as established by at least two ofthe four major rating services, and which mature not later, than 270 days from the purchase date. Such purchases may not exceed 10% of the issuer corporation's outstanding obligations.

Concentration of Credit Risk
The District's goal is to limit the amount that can be invested in commercial paper to one-third ofthe District's total investments, and no more than 20% ofthe amount invested in commercial paper can be invested in any one entity. In 2017. the fair value of commercial paper represented 27.6% ofthe District's total investments, including certificates of deposit. None ofthe District's commercial paper in any one entity exceeded the 20% goal.
As of December 31, 2017, the following investments were greater than 5% of total investments (in thousands of dollars):
Investment Fair Value
Federal Home Loan Bank (FHLB) \ S 93,230
Federal Home Loan Mortgage Corporation (FHLMC) 89,473 Illinois State Regional Transportation Authority 24,968

There are no investments that represent 5% or more of the Pension Trust Fund's net position restricted for pension benefits identified.
There are no individual investments held by the OPEB Trust that represent 5% or more of the Trust's fiduciary net position or the investment portfolio at year-end.
Custodial Credit Risk
The District's investments are not exposed to custodial credit risk since its investment policy requires all investments and investment collateral lo be held in safekeeping by a third party custodial institution, as designated by the Treasurer, in the District's name. Custodial credit risk is the risk that, in the event ofthe failure ofthe counterparty, the District will not be able to recover the value of its investments or collateral securities which are in the possession ofthe outside party.
As of December 31,2017, the Pension Trust Fund had minimal exposure to custodial credit risk since all investments were insured, registered, and/or held in the Fund's name.
The OPEB Trust's Investment Policy requires that all investments and investment collateral beheld in safekeeping by a third party custodial institution, as designated by the Treasurer, in the Trust's name. All cash balances maintained at banks arc required to be collateralized with permitted U.S. Government Securities in an amount equal to 105% (at market) ofthe monies on deposit. Cash awaiting reinvestment in the Trust's investment account is protected up to $250,000 under coverage by the Securities Investor Protection Corporation (SIPC). As of December 31, 2017, the Trust had no exposure to custodial credit risk since all investments were registered or held in the Trust's name.

Trust Fund Investments
The Pension Trust Fund uses the "prudent person rule" as the Fund's investment authority as set forth in the Illinois Compiled Statutes. The Fund's asset allocation policy allows investments in domestic equities, international equities and fixed income securities.
The OPEB Trust Fund is authorized under State Statute 70 ILCS 2605/9.6(d). In accordance with the Statute, the Trust Fund shall be managed by the District Treasurer in any manner deemed appropriate subject only to the prudent person standard. The Trust adopted its investment policy on November 19. 2009, and revised it on December 19. 2013. Investments shall be limited to publicly traded securities and mutual funds, adequately diversified among various market segments and sectors as well as other developed countries and emerging markets.

At December 31, 2017, the OPEB Trust's assets were invested in mutual funds traded on national securities exchanges. Investments are stated at fair value. The fair value of mutual fund units traded on national securities exchanges is the last reported sales price on the last business day ofthe fiscal year ofthe Trust. Purchases and sales of mutual fund units are accounted for on the trade dates.
Interest Rate Risk
Interest rate risk is defined as the risk that the fair value of an investment will be adversely affected by changes in market interest rates. Generally, the longer the maturity of an investment, the greater the sensitivity of its fair value to changes in market interest rates becomes. One strategy to manage exposure to interest rate risk is lo purchase a combination of short-term and long-term investments, while considering cash flow needs of the Pension Trust Fund. The Pension Trust Fund does not maintain an investment policy relative to interest rate risk; however, the Board of Trustees recognizes that its investments are subject to short-term volatility and their goal is to maximize total return within prudent risk parameters.

The OPEB Trust Fund's policy is to disclose any investment denomination in a foreign currency. Exposure to foreign currency risk is limited to the international investment allocation target maximum of 20% ofthe fair value of the investment portfolio.

Securities Lending
The Pension Trust Fund lends its secunties.to broker-dealers and other entities with a simultaneous agreement to return the collateral for the same securities in the future. The Bank of New York Mellon, the Fund's master custodian, lends for collateral in the form of cash, irrevocable letters of credit or other securities worth at least 102% ofthe lent securities' market value, and international securities for collateral worth at least 105%. The contract with the Fund's master custodian requires it to indemnify the Fund if the borrowers fail to return the securities (and if the collateral is inadequate to replace the securities lent) or fail to pay the Fund for income distributions by the securities issuers while the securities are out on loan.
All securities loans can be terminated on demand by either the Pension Trust Fund or the borrower, although the average term ofthe loans is one week. Cash collateral is invested in the lending agent's short-term investment pool, which at year-end has a weighted average maturity of 3 days.
The relationship between the maturities ofthe investment pool and the Pension Trust Fund's loans is affected by the maturities ofthe securities loans made by other entities that use the agent's pool, which the Fund cannot

determine. The Pension Trust Fund cannot pledge or sell collateral securities without borrower default; as such, the collateral security or non-cash collateral is not reported in the financial statements.
Although the Fund's securities lending activities are collateralized as described above, they involve both market and credit risk. In this context, market risk refers to the possibility that the borrower of securities will be unable to collateralize the loan upon a sudden material change in the fair value ofthe loaned securities or the collateral. Credit risk refers to the possibility that counterparties involved in the securities lending program may fail to perform in accordance with the terms of their contracts.
Indemnification deals with the situation in which a client's securities are not returned due to the insolvency of a borrower. The contract with the lending agent requires it to indemnify the Fund if borrowers fail to return the securities or fail to pay the Fund for income distributions by the issuers of securities while the securities are on loan.

A summary of securities loaned at fair value as of December 31, 2017 is as follows:
Fair value of securities loaned for cash collateral $ 26,675,638
Fair value of securities loaned for non-cash collateral 32,031,506
Total fair value of securities loaned $ 58,707,144

Fair value of cash collateral from borrowers $ 27,447,849
Fair value of non-cash collateral from borrowers 32,788,709
Total fair value of collateral $ 60,236,558

The value ofthe cash collateral held and a corresponding liability to return the collateral have been reported in the accompanying statement of fiduciary net position.
The fund also participates in the securities lending programs offered by State Street Global Advisors (SSGA) with regards to their commingled index funds. Securities lending income earned by SSGA serves as a credit to quarterly management fees, and any remainder is used for purchasing additional units in the bond index fund.
Fair Market Value Measurements
The District, the Pension Trust Fund and the OPEB Trust Fund have adopted GASB Statement No. 72, Fair Value Measurement and Application, which provides guidance for determining a fair value measurement for reporting purposes and applying fair value to certain investments and disclosures related to all fair value measurements.
The District and its fiduciary funds categorize its fair value measurements within the fair value hierarchy established by generally accepted accounting principles. The hierarchy is based on the valuation input used to measure the fair value ofthe asset.
Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for
identical assets. Includes common stock, mutual and commingled equity funds, and U.S.
Government and government agency obligations and Non-U.S. Government obligations that are
/ traded in active markets and are valued at closing prices on the measurement date.
Level 2 Quoted prices for similar assets or liabilities in active markets, inactive markets, or using other significant inputs which arc observable cither directly or indirectly. Includes U.S. Government and government agency obligations, non-U.S. Government obligations, mortgage backed securities, asset backed securities, and corporate bonds and notes that are generally valued by benchmarking model-derived prices to quoted market prices and trade data for identical or

comparable securities. To the extent that quoted prices are not available, fair value is determined based on a valuation model that includes inputs such as interest rates and yield curves at commonly quoted intervals, implied volatilities and credit spreads, or market corroborated inputs.
Prices or valuations that require inputs that are both significant to the fair value measurement and arc unobservable. Includes corporate bonds and notes that are valued using a discounted cash flow technique or consensus pricing.

7. Pension Plan Plan Description
The Metropolitan Water Reclamation District Retirement Fund (Pension Trust Fund) is the administrator of a single employer defined benefit pension plan (Plan) in accordance with 40 ILCS 5 ofthe Illinois Compiled Statutes. Article 13 ofthe Illinois Pension code grants the authority to establish the defined benefits ofthe Plan, as well as the employer and employee contribution levels ofthe Plan and may be amended only by the Illinois Legislature. The District contribution is currently calculated in accordance with stale statute as to the amount sufficient to meel the Fund's actuarially determined contribution requirement, but not to exceed an amount equal to 4.19 times the employee contributions two years prior. For the year ended December 31,2017, the District's average contribution rate was 40% of annual payroll. The District's actual contribution to the Retirement Fund was $89,858,000.
The Pension Trust Fund issues a financial report that includes financial statements and required supplementary information establishing the financial position of the Plan. That report may be obtained by writing to the Metropolitan Water Reclamation District Retirement Fund, 111 E. Erie, Chicago, IL, 60611-2898 or electronically on their website: www. mwrdrf.org .
The Pension Trust Fund provides retirement, death, and disability benefits to plan members and beneficiaries. Pension legislation (Public Act 96-0889) was approved in 2010 and established two tiers of members with different eligibility conditions and benefit provisions:
Tier 1 - Employees hired before January 1, 2011 are required to contribute 12% of their salary to the Fund. Tier 2 - Employees hired on or after January 1,2011 are required lo contribute 9% of their salary to the Fund.
The District is required to contribute the remaining amounts necessary to finance the requirements ofthe Plan on an actuarially funded basis.
Retirement Eligibility and Benefits
All full time employees ofthe District are eligible to participate in the retirement plan.
Tier 1 employees must have at least live years of service at age 60 and include service of 120 days or more per year to receive an undiscountcd retirement benefit. Employees in this tier who reach age 55 (or 50 if hired on or before June 13, 1997) with at least ten years of service are entitled to receive a minimum retirement benefit; however, if the employee is less than age 60 or service less than 30 years, the normal retirement benefit is reduced by .5% for each full month the member is less than age 60 or service is less than 30 years, whichever is less. Upon withdrawal from service a Tier I employee age 55 or under (50 if hired on or before June 13, 1997) and less than age 60 with less than 20 years of service, or age 60 or over with less than 5 years of service, is eligible for a refund of accumulated employee contributions, without interest, upon request. The retirement benefit is calculated as 2.2% ofthe final average salary for each ofthe first 20 years of service and 2.4% for each year of service in excess of 20 years. The benefit shall not exceed 80% of final average salary. Tier 1 employees receive a 3% cost of living adjustment annually.

Employees in this tier who reach age 62 with at least ten years of service arc entitled to receive a minimum retirement benefit; however, if the employee is less than age 67. the normal retirement benefit is reduced by .5% for each full month the member is less than age 67. A Tier 2 employee is eligible for a refund of accumulated employee contributions without interest if under age 62 regardless of service, or if less than 10 years of service regardless of age on withdrawal. Ihe retirement benefit is calculated as 2.2% ofthe final average salary for each ofthe first 20 years of service and 2.4% for each year ol service in excess of 20 years.

receive a cost of living adjustment as the lesser of 3% and halfof the CPI-u for the 12 months ending the September 30th prior to the increase date.
If a covered employee leaves employment before the age of 55, accumulated employee contributions are refundable without interest. Upon receipt of a refund, the employee forfeits rights to benefits from the fund.
There are two other types of annuities available to family members ofthe plan: Surviving Spouse Annuity and Children's Annuity. The spouses of employees hired before June 13, 1997 arc immediately eligible to receive a surviving spouse annuity; spouses of employees hired on or after June 13, 1997 are eligible after three years of member's service. For all Tier 1 employees hired before January I, 2011, the surviving spouse annuity is equal to 60% ofthe employee's retirement benefit at the time of death plus 1 % for each year of total service to a maximum of 85%. For Tier 2 employees, an eligible surviving spouse will be entitled to an annuity equal to 66 2/3% of the employee's retirement benefit at time of death. Each unmarried child, until the age of 18 (23 if full time student) of an employee that dies in service or of a former member that dies with at least ten years of service, is eligible for a monthly annuity of $500 per month (if one parent is living) and S1,000 per month (if neither parent is living) to a maximum total benefit of $5,000 per month.

For purposes of measuring the net pension liability, deferred outflows of resources and deferred inflows of resources related to pensions, and pension expense, information about the fiduciary net position the Pension Plan and additions to/ deductions from the Pension Plan's fiduciary net position have been determined on the same basis as they are reported by the Pension Plan. For this purpose, benefit payments (including refunds of employee contributions) are recognized when due and payable in accordance with the benefit terms. Investments are reported at fair value. Detailed information about the pension plan's fiduciary net position is available in the separately issued Retirement Fund financial report.

Actuarial Methods and Assumptions
The District's net pension liability was measured as of December 31, 2016, and the total pension liability used to calculate the net pension liability was determined by an actuarial valuation as of December 31, 2016. The District chose to use a measurement date one year in arrears. The total pension liability in the December 31,2016 actuarial valuation was determined using the Entry Age Normal actuarial cost method and using the following actuarial assumptions, applied to all periods included in the measurement:
Inflation Salary Increases Investment Rate of Return Cost of living adjustment
2.5%
Varies by service
7.50%. net of investment expense, including inflation Tier 1: 3%
Tier 2:' the lesser of 3% and half of the CPI-u for the 12 months ending the September 30th prior to the increase date
Surviving spouse annuitants: 1.25%

Mortality rates were based on the RP-2000 Combined Healthy Mortality Tables with generational mortality improvements based on Scale AA. Pre-retirement mortality rates are the same as post-retirement rates.
The actuarial assumptions used in the December 31, 2015 valuation were based on the results of an actuarial experience study for a five year period ending December 31, 2013.
Investment Allocation and Rate of Return
The long-term expected rate of return on pension plan investments was determined using a building-block method which best estimates ranges of expected future real rates of return. These ranges are combined to produce the long term expected rate of return by weighting the expected future real rates of return by the target asset allocation percentage and by adding expected inflation. The Pension Board's adopted target asset allocation and best estimates of real rates of return for each major asset class are summarized in the following table:
Expected
Asset Class Target Allocation Real Rate of Return
Domestic Equity 42% 5%
International Equity 23%' 5.1%
Bonds 35% 0.4%

The discount rate used to measure the total pension liability was 7.5%. The projection of cash flows used to determine the discount rate assumed that plan member contributions will be made at the current contribution rate and that sponsor contributions will be made at rales equal to the difference between actuarially determined contribution rates and the member rale. Based on those assumptions, the pension plan's fiduciary net position was

projected to be available to make all projected future benefit payments of current plan members; therefore, the long term expected rate of return of 7.5% was applied to all periods of projected benefit payments to determine the pension liability.
A sensitivity analysis is also completed lo show the effect on the net pension liability if the discount rale was plus or minus one percentage point from the current rate (in thousands of dollars):
I % Decrease Current Discount 1% Increase
6.5% Rate of 7.5% 8.5%
Net Pension Liability ~$ 1,361,929 $ 1,079,566 $ 841,925
Payable to the Pension Plan and Pension Expense
At December 31, 2017, the District reported a payable of $89,858^000 for the outstanding amount of contributions to the pension plan required for the year ended December 31, 2017. The pension expense for the year ended December 31, 2017 was $117,336,000.
8. OPEB - Other Post-Employment Benefits Plan Description
The Metropolitan Water Reclamation District Retiree Health Care Trust (OPEB Trust) administers the financing and payment of other post employment benefits for the Metropolitan Water Reclamation District of Greater Chicago. Pursuant to Illinois Statute 70 ILCS 2605/9.6(d), the District adopted the Metropolitan Water Reclamation District Retiree Health Care Plan (Plan) effective December 6, 2007. The purpose ofthe Plan is to provide postretirement medical and prescription drug coverage benefits to retirees as well as spouses and dependents of retirees that fulfill certain eligibility requirements. Retirees and annuitants receiving a pension through the Pension Trust fund are eligible for District sponsored health insurance. As of December 31,2017, there are 2,797 retirees and beneficiaries currently receiving health care coverage.
The OPEB Trust Fund issues a financial report that includes financial statements and required supplementary information establishing the financial position of the Plan. That report may be obtained by writing to the Metropolitan Water Reclamation District Retiree Health Care Trust Fund, 100 E. Erie, Chicago, IL, 60611-2898 or electronically on the District's website: www.mwrd.org .
Basis of Accounting
The financial statements ofthe Trust are prepared using the accrual basis of accounting. Employer contributions to the Trust are recognized when due and the employer has made a formal commitment to provide the contributions. Benefits and refunds are recognized when due and payable in accordance with the terms ofthe Plan.
Contributions
The District has not entered into any long-term contracts for contributions to the plan as ofthe date of this report. State Statute 70 ILCS 2605/9.6d is the legislation establishing the Trust and gives the District Boanl of Commissioners discretionary authority to determine contribution amounts to be paid by the District. The OPEB Funding Policy includes a target funded ratio of 100% with an expected funding period of 12 years (beginning in 2015). In 201 7, $5,000,000 was contributed by the District to the OPEB Trust Fund bringing the total contributed through December 31, 2017 to $127,400,000. In succeeding fiscal years, the Trust will receive the District (employer) contribution as determined by the Board of Commissioners. There is currently no requirement for the District to partially or fully fund the Trust, and any funding is on a voluntary basis. Plan participants do not contribute to the plan other than providing premium contributions as discussed below.

The District allows employees who retire and meet certain eligibility requirements to continue medical coverage as participants in the Metropolitan Water Reclamation District Retiree Health Care Plan. The plan allows for subsidized health care benefits for its retirees. Retirees contribute 39.0% ofthe premium and the District pays the remaining 61.0%. Each year for the next five years, retiree contributions will rise by 2.5% until the premium reaches 50%. Annually, the Board approves an appropriation to fund retiree medical costs as part ofthe Human Resources Department. General Corporate Fund budget. The amount of OPEB expenditure recognized during 2017 by the District was $18,430,657, all claims paid (net of participant contributions).

Actuarial Methods and Assumptions
Actuarial valuations of an ongoing plan involve estimates ofthe value of reported amounts and assumptions about the probability of occurrence of events far into the future. Examples include assumptions about future employment, mortality, and the health care cost trend. Actuarially determined amounts arc subject to continual revision as actual results are compared with past expectations and new estimates are made about the future. The schedule of funding progress, presented as required supplementary information following the notes lo the financial statements, compares whether the actuarial values of plan assets arc increasing or decreasing over time relative lo the actuarial accrued liabilities for benefits.
The accompanying schedules of employer contributions present trend information about the amounts actually contributed to the plan by employers in comparison to the Annual Required Contribution (ARC), an amount that is actuarially determined in accordance with the parameters of GASB Statement 45, "Accounting and Financial Reporting by Employers for Postemploymcnt Benefits Other Than Pensions". The ARC represents a level of funding that, if paid on an ongoing basis, is projected lo cover normal cost for each year and amortize any unfunded actuarial liabilities (or funding excess) over a period not to exceed thirty years.
Projections of benefits for financial reporting purposes are based on the substantive plan (the plan as understood by the employer and plan members) and include the types of benefits provided at the time of each valuation and the historical pattern of sharing of benefit costs between the employer and plan members to that point. The actuarial

100 FINANCIAL SECTION

methods and assumptions used include techniques that arc designed to reduce the effects of short-term volatility in actuarial accrued liabilities and the actuarial value of assets, consistent with the long-term perspective ofthe calculations.
The annual required contribution for the current year actuarial valuation uses the entry age normal actuarial cost method and the level percentage of payroll amortization method. Additional assumptions arc summarized in the following table:

9. Commitments and Rebatable Arbitrage Earnings
The General Corporate Fund has existing purchase order encumbrances of SI,049,694 at December 31, 2017. Construction, Stormwater Management, and Capital Improvements Bond Funds' contract commitments (encumbrances) were $290,252,000 at December 31, 2017. State Revolving Fund Loan commitments of $ 104,982,000 at December 31, 201 7, arc also collectible as contract expenditures are incurred.
The Internal Revenue Code requires that an issuer of tax-exempt bonds rebate to the United States any excess investment earnings made with the gross proceeds of an issue over the amount which would have been earned had such proceeds been invested at a rate equal to the yield on the issue. The Internal Revenue Code offers certain "safe harbors" permitting qualified governments to keep extra earnings that result from arbitrage. The District has made a determination of their probable liability for amounts potentially due to the United States government. As of December 31. 2017, the District has no arbitrage rebate liability.

National Pollutant Discharge Elimination System
NPDES Permits. The District operates its water reclamation plants (the "WRPs") in accordance with National Pollutant Discharge Elimination System ("NPDES") permits issued by the IEPA. After several years and substantial litigation, the IEPA reissued the District's NPDES permits for the Stickney, Calumet and O'Brien WRPs. These permits include three special conditions agreed upon by the District and several non-governmental organizations to settle the ongoing litigation on these three NPDES permits. Under these additional conditions, the District will fund a super-gauge to monitor nutrients in the lower Des Plaines River (estimated lo be approximately 5270,000 over the next four years), hire a consultant to prepare an implementation plan to address phosphorous in area waterways, and potentially implement that plan. The District will also have to conduct a feasibility study to determine the cost of reducing phosphorous in the WRPs' effluent to certain levels. If required to reduce the phosphorous in the District's effluent to very low levels, the costs could be substantial.

The District's NPDES permits for the Kirie, Hanover Park, Lemont, and Egan WRPs have not yet been reissued.
NPDES Consent Decree. The District's NPDES permits, in addition to controlling discharges from the WRPs, also impose conditions upon combined sewer system overflows (the "CSOs"). In compliance with the NPDES permits, the District's TARP was developed as a long term control plan to control CSOs. The USEPA alleged that discharges from the District's CSOs have and continue to violate certain permit requirements, including the prohibition on discharging pollutants into waters that cause or contribute to violations of applicable water quality standards for dissolved oxygen, solids, and tloatablcs. IEPAjoincd the USEPA in alleging the stated water quality violations. Entities with combined sewer systems that allegedly are in violation of applicable water quality standards are subject lo an enforceable schedule for the implementation of a long term control plan, with "enforceable" requiring a judgment or a consent decree entered in a federal district court.
In December 2011, the USEPA and IEPA filed a lawsuit against the District for the alleged violations, and lodged a consent decree negotiated between the USEPA, IEPA and the District. The case is captioned United States of America and State of Illinois v. Metropolitan Water Reclamation District of Greater Chicago, 11 CV 08859. Without an admission of liability, the consent decree resolved the federal and state claims associated with the District's CSOs. The consent decree, among other things: (a) establishes a construction schedule with interim milestones for completion and operation of portions ofthe District's TARP plan; (b) obligates the District to advance funds to the U.S. Army Corps of Engineers (the "Corps") for portions of the District's TARP for which the Corps is responsible should federal funds be unavailable to the Corps by the stated deadlines; (c) establishes performance criteria and develops post-construction monitoring for portions ofthe TARP system; (d) requires the District lo continue seasonal operation of debris boats and pontoon boats to control floatablcs in the CAWS; (c) requires the District to submit annual reports on its compliance with the terms of the consent decree; (f) imposes stipulated penalties for violations ofthe decree; (g) imposes a total civil penalty of $675,000, which the District has already paid; (h) requires Ihe District lo implement one or more green infrastructure projects within one year fora minimum of $325,000, which the District has done; and (i) to implement additional green infrastructure projects staggered over the next 15 years that provide a minimum of 10 million gallons of design retention capacity in an individual storm, which the District continues to do.
NPDES Citizen Suit. In May 2011, the Natural Resources Defense Council. Sierra Cub, and Prairie Rivers Network (the "NGOs") filed a Clean Water Act ("CWA") citizen suit against the District in the District Court alleging violations of CWA-bascd water quality standards. The District vigorously defended against this lawsuit, and ultimately reached a settlement at the same time as it reached a settlement in the NPDES permit appeal pending before the IPCB. As part of this settlement, in addition to agreeing to recommend that the IEPA add three more special conditions into its NPDES permits for Stickney, Calumet, and O'Brien WRPs, the District agreed lo pay approximately $1.8 million to plaintiffs' attorneys in fees and costs. Upon the IPEA's reissuance ofthe Stickney, Calumet, and O'Brien WRP's NPDES permits, in October 201 7. the District paid the plaintiffs' fees and costs. This litigation has now concluded

Class Action Flooding Claims. The District has previously been and is presently a parly to several proposed class action lawsuits pending in the Circuit Court of Cook County arising out of local sewer back-ups and overland flooding resulting in basement flooding. The District is also in receipt of flooding claims in which lawsuits have not yet been filed. These lawsuits and claims are generally brought in tort, or for constitutional or statutory violations. As of the date of this CAFR, the Circuit Court of Cook County and the Illinois Appellate Court for the First District have ruled in the District's favor in every fully-adjudicated matter. A constitutional question was appealed to the Illinois Supreme Court, was answered, and remanded back to the Circuit Court for further proceedings. Other cases are currently on appeal to the Illinois Appellate Court for the First District.

10. Risk Management and Claims
The District is primarily self-insured for the "working layer" of losses and purchases excess insurance to assist in the response to catastrophic claims. Under the Reserve Claim Fund the District may levy an annual property tax not to exceed .005% of the equalized assessed valuation of taxable property within the District's territorial limits. The Reserve Claim Fund can be used for the payment of claims, awards, losses, judgments, liabilities, settlements, or demands and associated attorney's fees and costs that might be imposed on or incurred by such sanitary district in matters including, but not limited to, the Workers' Compensation Act or the Workers' Occupational Diseases Act, any claim in tort, any claim of deprivation of any constitutional or statutory right or protection, for all expenses, fees, and costs, both direct and in support of any property owned by such sanitary district which is damaged by fire, flood, explosion, vandalism or any other peril, natural or manmadc. The aggregate amount that may accumulate in the Reserve Claim Fund cannot exceed .05% of the equalized assessed valuation. The Reserve Claim Fund accounts are included in the General Corporate Fund as described in Note 1 .b to the financial statements.
From time to time, the District may be involved in various litigation relating to claims arising from general liability, property damage, automobile liability, personal injury, employment practices, marine liability, and public officials liability. The majority of these claims and judgments would be covered by insurance or paid from the Reserve Claim Fund accounts.
The District may be involved in various litigation relating to claims arising from construction contracts. Construction related liability claims can typically be tendered to the Contractor for defense and indemnification. Most other claims and judgments involving disputed construction contracts would be paid by the Capital Improvements Bond or Construction Funds.
The District may also be involved in various litigation for claims relating to environmental regulations. Under current environmental protection laws, the District may be ultimately responsible for the environmental remediation of some of its leased-out properties. The District has developed a preliminary estimate of environmental remediation costs for major lease sites. The range of such estimated costs at December 31, 2017, is between S26.5 million and $39.4 million. The District is ofthe opinion that the tenants (except for those who are bankrupt, out of business, or otherwise financially unable to perform) would ultimately be liable for the bulk, if not all, of these site clean­up costs. Negotiations are ongoing between the District's lawyers and the tenants to resolve remedial activity and cost liability issues. The current estimated cost was determined to be $3 1,575,000 with an estimated cost recoverable amount of $22,150,000 resulting m $9,425,000 being recognized at December 31, 2017 in the liabilities of the government-wide financial statements. Of this amount, none of the current liability is classified as short-term and $9,425,000 is considered a long-term liability These estimates are subject to changes as a result of price increases, changes in technology and new laws and regulations. These estimates were generated using the expected cash Hows technique. GASB Statement No. 49 addresses accounting and financial reporting standards for pollution (including contamination) remediation obligations, which are obligations to address the current or potential detrimental effects of existing pollution by participating in pollution remediation activities such as site assessments and cleanups. The scope ofthe document excludes pollution prevention or control obligations with respect to current operations, and future pollution remediation activities that are required upon retirement of an asset.

The most recent such authorization was pursuant to a bond ordinance adopted in calendar year 2016 in the amount of $500,000,000 for Capital Improvement Bonds, 2016 IEPA Series. The IEPA approves various capital improvements related to sewage treatment works and Hood control facilities for funding from the State Water Pollution Control Revolving Loan Fund (SRF). Once a project has been approved, the State offers the District a loan from the State's Revolving Loan Fund, which the District incorporates into the form of the bond which is issued to the IEPA (the Loan/Bond). When work on the project begins, the District pays the contractor. The District receives a corresponding amount of advance on the Loan/Bond from the IEPA. This form of loan is commonly referred to as a drawdown loan. The advances continue on the Loan/Bond until the project is completed or the amount of the loan fully advances, whichever occurs first. In general, within two years ofthe first advance on a Loan/Bond, the IEPA promulgates a repayment schedule on such Loan/Bond. The repayment schedules call for level payments of principal and interest, collectively, over a 20 year period beginning within six months ofthe date the repayment schedule is promulgated. Under this authority, the IEPA has approved the following loan amount:
2017 S 16,700,000

Modified Approach for Eligible Infrastructure Assets
The District has elected to use the modified approach to report eligible infrastructure and ancillary assets at its seven water reclamation plants (WRP) and its waterway assets. Each of the seven plants represents a separate network, while the waterway assets represent an eighth network. The eight networks are as follows:
O'Brien WRP Basin
Calumet WRP Basin
Egan WRP Basin
Kirie WRP Basin
Hanover Park WRP Basin
Lemont WRP Basin
Waterways

1. Central (Stickney) WRP Basin All systems, subsystems, and components associated with the Central (Stickney)
WRP service area (excluding Waterways Network assets).

All systems, subsystems, and components associated with the O'Brien WRP service area (excluding Waterways Network assets).

All systems, subsystems, and components associated with the Calumet WRP service area (excluding Waterways Network assets and Lemont Network).

All systems, subsystems, and components associated with the Egan WRP service area (excluding Waterways Network assets).

All systems, subsystems, and components associated with the Kirie WRP service area (excluding Waterways Network assets).

All systems, sub-systems, and components associated with the Hanover Park WRP service area (excluding Waterways Network assets).

All systems, subsystems, and components associated with the Lemont WRP service area (excluding Waterways Network assets).

All waterways under the jurisdiction of the District including the Waterways Control System, Lockport Powerhouse and Controlling Works, Chicago River Controlling Works, Wilmette Pumping Station, all District flood control reservoirs and pump stations, sidestrcam elevated pool aeration stations, instream aeration stations, Melas Park, and Centennial Fountain.

Each ofthe above networks is further segregated into systems, subsystems, and components. The network systems are classified by the process How through the network (i.e., collection processes, treatment processes, solids processing, flood and pollution control, and solids drying/utilization). The subsystems of each system represent the major processes (e.g., the treatment processes system includes fine screens, grit tanks, and aeration tanks as subsystems). Components of subsystems comprise the working unit or assembly (e.g., the fine screens subsystem includes conveyors, rakes, and gates as components). Ratings are determined by District civil, mechanical, and electrical engineers, who review the subsystem/component maintenance records and physically inspect the assets.










116 FINANCIAL SECTION
Metropolitan Water Reclamation District of Greater Chicago




Ratings are assessed at the subsystem level and are compiled for reporting puiposes into one rating for each system of a network. The assessment scale used to rate the networks' systems is as follows:

Assessment Description

Relatively new asset or recently rehabilitated or otherwise restored to a like-new asset condition.
(2) Very Good
Good
Acceptable
Fair
Performance successful, operation reliable, no significant maintenance required beyond routine preventative maintenance or minor repair in foreseeable future.

Performance-successful, operation reliable, significant maintenance required in foreseeable future.

Performance successful, operation reliable, significant rehabilitation/ replacement planned in near future.

Performance marginal, operation not reliable without immediate repair/ replacement.

Inoperable or operation significantly impaired.

It is the District's policy to maintain eligible infrastructure assets reported under the modified approach at a level of acceptable or better.
Initial condition assessments ofthe Kirie, Hanover, Egan, O' Brien, Central (Stickney), Calumet, Lemont and Waterways WRP networks were completed between 2002 and 2006.
Condition assessments of each network will continue at least every three years following the initial assessment. The Kirie, Central (Stickney), and Waterways networks were re-assessed in 2017, the Hanover, Calumet, and Lemont networks were re-assessed in 2015 and the Egan and O'Brien networks were re-assessed in 2016.

Report on Internal Control Over Financial Reporting and on Compliance and Other Matters Based on an Audit of Financial Statements Performed in Accordance With Government Auditing Standards

To the Honorable President and Members of the Board of Commissioners Metropolitan Water Reclamation District of Greater Chicago

We have audited, in accordance with auditing standards generally accepted in the United States of America and the standards applicable to financial audits contained in Government Auditing Standards issued by the Comptroller General of the United States, the financial statements of the governmental activities, each major fund and the aggregate remaining fund information of Metropolitan Water Reclamation District of Greater Chicago (the District), as of and for the year ended December 31, 2017, and the related notes to the financial statements, and the respective changes in financial position thereof and the respective budgetary comparisons for the General Corporate Fund and the Retirement Fund for the year then ended, which collectively comprise the District's basic financial statements, and have issued our report thereon dated May 11, 2018. Our report includes a reference to other auditors who audited the financial statements of the District's Pension Trust Fund as described in our report on the District's financial statements. This report does not include the results of the other auditors' testing of internal control over financial reporting or compliance and other matters that are reported separately by those auditors.
Internal Control Over Financial Reporting
In planning and performing our audit ofthe financial statements, we considered the District's internal control over financial reporting (internal control) to determine the audit procedures that are appropriate in the circumstances for the purpose of expressing our opinions on the financial statements, but not for the purpose of expressing an opinion on the effectiveness of the District's internal control. Accordingly, we do not express an opinion on the effectiveness of the District's internal control.
A deficiency in internal control exists when the design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent, or detect and correct, misstatements on a timely basis. A material weakness is a deficiency, or a combination of deficiencies, in internal control, such that there is a reasonable possibility that a material misstatement of the entity's financial statements will not be prevented, or detected and corrected on a timely basis. A significant deficiency is a deficiency, or a combination of deficiencies, in internal control that is less severe than a material weakness, yet important enough to merit attention by those charged with governance.
Our consideration of internal control was for the limited purpose described in the first paragraph of this section and was not designed to identify all deficiencies in internal control that might be material weaknesses or significant deficiencies. Given these limitations, during our audit we did not identify any deficiencies in internal control that we consider to be material weaknesses. However, material weaknesses may exist that have not been identified.


THE POWER OF BEING UNDERSTOOD
-¦¦UD " SAX : CONSULTING





180 SINGLE AUDIT SECTION

Compliance and Other Matters
As part of obtaining reasonable assurance about whether the District's financial statements are free from material misstatement, we performed tests of its compliance with certain provisions of laws, regulations, contracts, and grant agreements, noncompliance with which could have a direct and material effect on the determination of financial statement amounts. However, providing an opinion on compliance with those provisions was not an objective of our audit, and accordingly, we do not express such an opinion.

INDEPENDENT AUDITORS'REPORT ON COMPLIANCE FOR EACH MAJOR PROGRAM AND ON INTERNAL CONTROL OVER COMPLIANCE REQUIRED BY
THE UNIFORM GUIDANCE


The Honorable President and
Members of the Board of Commissioners
Metropolitan Water Reclamation District of Greater Chicago


Report on Compliance for the Major Federal Program

We have audited the Metropolitan Water Reclamation District of Greater Chicago's (the "District") compliance with the types of compliance requirements described in the OMB Compliance Supplement that could have a direct and material effect on the District's major federal program for the year ended December 31,2017. The District's major federal program is identified in the summary of auditor's results section of the accompanying schedule of findings and questioned costs.
Management's Responsibility
Management is responsible for compliance with the federal statutes, regulations, and the terms and conditions of its federal awards applicable to its federal programs.
Auditor's Responsibility
Our responsibility is to express an opinion on compliance for the District's major federal program based on our audit ofthe types of compliance requirements referred to above. Wc conducted our audit of compliance in accordance with auditing standards generally accepted in the United States of America; the standards applicable to financial audits contained in Government Auditing Standards, issued by the Comptroller General ofthe United States; and the audit requirements of Title 2 U.S. Code of Federal Regulations Part 200, Uniform Administrative Requirements, Costs -Principles, and Audit Requirements for Federal Awards (Uniform Guidance). Those standards and the Uniform Guidance require that we plan and perform the audit to obtain reasonable assurance about whether noncompliance with the types of compliance requirements referred to above that could have a direct and material effect on a major federal program occurred. An audit includes examining, on a test basis, evidence about the District's compliance with those requirements and performing such other procedures as we considered necessary in (he circumstances.
We believe that our audit provides a reasonable basis for our opinion on compliance for the major federal program. However, our audit does not provide a legal determination of the District's compliance.








184 SINGLE AUDIT SECTION
(
Opinion on the Major Federal Program
In our opinion, the District complied, in all material respects, with the types of compliance requirements referred to above that could have a direct and material effect on its major federal program for the year ended December 31, 2017.

Report on Internal Control over Compliance
Management of the District is responsible for establishing and maintaining effective internal control over compliance with the types of compliance requirements referred to above. In planning and performing our audit of compliance, we considered the District's internal control over compliance with the types of requirements that could have a direct and material effect on the major federal program to determine the auditing procedures that are appropriate in the circumstances for the purpose of expressing an opinion on compliance for the major federal program and to test and report on internal control over compliance in accordance with the Uniform Guidance, but not for the purpose of expressing an opinion on the effectiveness of internal control over compliance. Accordingly, wc do not express an opinion on the effectiveness of the District's internal control over compliance.
A deficiency in internal control over compliance exists when the design or operation of a control over compliance does not allow management or employees, in the normal course of performing their assigned functions, to prevent, ordetect and correct, noncompliance withatypeofcompliance requirement of a federal program on a timely basis. A material weakness in internal control over compliance is a deficiency, or combination of deficiencies, in internal control over compliance, such that there is a reasonable possibility that material noncompliance with a type of compliance requirement of a federal program will not be prevented, or detected and corrected, on a timely basis, ^.significant deficiency in internal control over compliance is a deficiency, or a combination of deficiencies, in internal control over compliance with a type of compliance requirement of a federal program that is less severe than a material weakness in internal control over compliance, yet important enough to merit attention by those charged with governance.
Our consideration of internal control over compliance was for the limited purpose described in the first paragraph of this section and was not designed to identify all deficiencies in internal control over compliance that might be material weaknesses or significant deficiencies. Wc did not identify any deficiencies in internal control over compliance that we consider to be material weaknesses. However, material weaknesses may exist that have not been identified.
Chicago, Illinois May 11, 2018
The purpose of this report on internal control over compliance is solely to describe the scope of our testing of internal control over compliance and the results of that testing based on the requirements ofthe Uniform Guidance. Accordingly, this report is not suitable foranyotherpurpo.se .
